"Term shifting", "merging" and "coefficient to 1" all change a more complex one variable linear equation, such as 2x-19 = 7x + 31, into the simplest one variable linear equation, such as x = - 10. Can you change the equation AX + B = CX + D (x is unknown, a, B, C, D is known, and a ≠ C) into the simplest one variable linear equation?

"Term shifting", "merging" and "coefficient to 1" all change a more complex one variable linear equation, such as 2x-19 = 7x + 31, into the simplest one variable linear equation, such as x = - 10. Can you change the equation AX + B = CX + D (x is unknown, a, B, C, D is known, and a ≠ C) into the simplest one variable linear equation?

The results show that: ax CX = D-B, x = D-B, ∵ a ≠ C, x = D − BA − C

How to solve the equation 15 △ 3x = 0.5
The original equation is as follows:
15/3x=0.5
3x=15/0.5
3x=30
x=10
Because x can't be zero, multiply both sides by 3x to get x = 10
Hello!
Gu Ge 22 for you
15+3x=0.5
The deformation of the original equation is: 15 △ 3x = 0.5
3x=15÷0.5
3x=30
x=30÷3
x=10
Hope to adopt.
1 / 3x + 300 = 0.4x is a solution to the equation,
0.4x-1/3x=300
(0.4-1/3)x=300
1/15x=300
x=300÷1/15
x=4500
1/3x+300=0.4x
Multiply by 3 to get x + 900 = 1.2x
1.2x-x=900
0.2x=900
x=4500
1/3x+300=0.4x
1/3x+300=2/5x
(2 / 5-1 / 3) x = 300 (general score)
1/15x=300
x=4500

There are several real solutions to the equation 3x ^ 2 + 4x-6 / x + 5 = 0 of X,
There are several real solutions to the equation 3x ^ 2 + 4x-6 / x + 5 = 0 of X,
Let Y1 = 3x ^ 2 + 4x + 5 = 3 (x + 2 / 3) ^ 2 + 11 / 3
Function y2 = 6 / X
Drawing the two images shows that there is only one intersection point (in the first quadrant)
3x ^ 2 + 4x-6 / x + 5 = 0, there is only one intersection point between y = 3x ^ 2 + 4x + 5 and y = 6 / x, so there is only one real root?
