0.3x + 0.9 = 45.3

0.3x + 0.9 = 45.3

0.3x+0.9=45.3
0.3x=45.3-0.9
0.3x=44.4
x=44.4/0.3
x=444/3

The solution of equation 9-3X = 5x + 5 is the same as the solution of M = 9 of mx-2, and the value of M needs to be determined by the process

9-3x=5x+5
8x=4
When x = 1 / 2 is substituted into the latter equation, M / (1 / 2m-2) = 9
m=4.5m-18
3.5m=18
m=36/7

How to solve the equation 3x (6 + x) + 3x = 528

3x(6+x)+3x=528
18+3x+3x=528
18+6x=528
6x=510
x=510/6
x=85
Sorry, I don't know whether the X in "3x" is a multiplication sign or a letter X, so I do it by multiplication. If it's a letter X, the landlord can reply and I'll do it again

The solution of the equation 3x + X + 6 = 26

3x+x+6=26
4x+6=26
4x=20
x=5

How to translate the square of y = x to get the image of y = - 2x + 4x-3x

y=-2x^2+4x-3x=-2(x^2-1/2x+1/16)+1/8
A = - 2 opening downward
However, y = x ^ 2 cannot be obtained by moving the opening upward

The intersection coordinates of the line y = 2x + 2 and the parabola y = x2 + 3x are______ ．

∵ from the meaning of the problem, we get y = 2x + 2Y = x2 + 3x, and the solution is x = − 2Y = − 2 or x = 1y = 4. The intersection coordinates of the straight line y = 2x + 2 and the parabola y = x2 + 3x are (- 2, - 2), (1,4). So the answer is: (- 2, - 2), (1,4)

Find the intersection of parabola y = x square - 3x + 3 and straight line y = 2x-1

By substituting the straight line y = 2x-1 into the parabolic equation, we get
2x-1=x^2-3x+3
x^2-5x+4=0
(x-4)(x-1)=0
x=4 x=1
y=2*4-1=7 y=2*1-1=1
So the intersection is
(4,7) and (1,1)

The intersection coordinates of the square of parabola y = 2x + 3x -- 4 and straight line x = 4

When x = 4, y = 2 × 4 ^ 2 + 3 × 4-4 = 32 + 12-4 = 40
So the intersection coordinates are (4,40)

4.5-2 / 3x = 2 / 3
4.5-3 of 2x = 2 of 3, wrong number just now

2x/4.5-3=3/2
2x/4.5=9/2
4x/9=9/2
4x=81/2
x=81/8

3x of 2.4 = 3 of 5

3X/2.4=3/5
Multiply the numerator and denominator on the left side of the equation by 10 to get 30x / 24 = 3 / 5
It is reduced to 5x / 4 = 3 / 5
The solution is x = 12 / 25 = 12 / 25
Text description: 3x of 2.4 = 3 of 5
The numerator and denominator on the left side of the equation multiply by 10 to get 30x of 24 = 3 of 5
The left is reduced to 5 / 4 x = 3 / 5
That is 25X = 12
X = 12 / 25
