2x-4y-6 = 0, find 3x-6y + 5

2x-4y-6 = 0, find 3x-6y + 5

x-2y=3,
3(x-2y)+5 = 14

What is the solution process of equation 3x + 4x = 14?
Tell me more about it!

3x+4x=14
(3+4)x=14
7x=14
x=14/7
x=2

Solving the equation 3x + 9 = 4x + 2

3x+9=4x+2
4x-3x=9-2
x=7

5. The steps to solve the equation are as follows: 1) remove the denominator and get 3 (x + 1) - 2 (2-3x) = 1; 2) remove the brackets
It is found that 3x + 3-4-6x = 1
③ By changing the term, we get 3x-6x = 1-3 + 4
④ Combining the similar terms, we get - 3x = 2
⑤ If the coefficient is reduced to 1, x = -
(1) smart, do you know Xiao Li's answer process is correct? Answer: (fill in "yes" or "no"), if not, there is a problem in step (fill in the serial number);
Could you give me two suggestions on what Xiao Ling should pay attention to when solving the equation?
①：；
②：．
Please write down the correct answer to this question

No. (2) wrong sign. To remove the bracket should be 3x + 3-4 + 6x = 1, and (5) finally get x = - 2 / 31. Note that when removing the bracket, if there is a - sign outside the bracket, the sign inside the bracket will be changed (yes - sign will become + sign; yes + sign will become - sign). 2. Pay attention to the sign transformation when moving items! Correct answer process: 1. To remove the denominator, you will get 3 (x + 1) - 2 (...)

Xiao Li is solving the equation 2x-1 divided by 4 = x + m divided by 4-1 to the denominator. The - 1 on the right side of the equation is not multiplied by 4, so the solution is x = 3. Can you help Xiao Li find the correct solution of the equation

That is, 2x-1 = x + M-1
x=m
x=3
So m = 3
The correct formula is 2x-1 = x + M-4
x=m-3
So it's x = 0

One variable linear equation with denominator on the left and right are integers. After removing the denominator on the left, do you want to multiply the right by the least common multiple? Example x + 17 / 5-3x-7 / 4 = - 2

（ x+17）/5-（3x-7）/4=-2
Multiply the two sides of the equation by 20
4（x+17)-5(3x-7)=-40
4x+68-15x+35=-40
-11x+103=-40
Both sides + 11x + 40
11x=143
x=13

Solving exponential equation: (0.25) ^ 4x-1 = 2 ^ 1-3x

Your equation should be
(0.25) ^ (4x-1) = 2 ^ (1-3x)
(1/4)^（4x-1）=2^（1-3x）
Because 1 / 4 = 2 ^ (- 2)
SO 2 ^ (- 2) (4x-1) = 2 ^ (1-3x)
(-2)（4x-1）=（1-3x）
-8x+2=1-3x
x=0.2

Try to explain that x (x + 1) (x + 2) (x + 3) + 1 is a complete square formula

x(x+1)(x+2)(x+3)+1
=[x(x+3)][(x+1)(x+2)]+1
=(x²+3x)[(x²+3x)+2]+1
=(x²+3x)²+2(x²+3x)+1
=(x²+3x+1)²

It is proved that: (x + 1) (x + 2) (x + 3) (x + 4) + 1 is a complete square expression

(X+1)(X+2)(X+3)(X+4)+1
=[(X+1)(X+4)][(X+2)(X+3)]+1
=(X^2+5X+4)(X^2+5X+6)+1
=[(X^2+5X+5)-1][(X^2+5X+5)+1]+1
=(X^2+5X+5)^2-1+1
=(X^2+5X+5)^2

It is proved that x (x + 1) (x + 2) (x + 3) + 1 is a complete square expression

It's hard to write. (x (x + 3)) ((x + 1) (x + 2)) + 1
=（x^2+3x）(x^2+3X+2)+1
Take x ^ 2 + 3x as a whole and replace it with a
Original formula = a (a + 2) + 1 = a ^ 2 + 2A + 1 = (a + 1) ^ 2
Replace a with the original = (x ^ 2 + 3x + 1) ^ 2
