Question

What is the answer to this equation y=4x+8x for x

Answer 1

Solve for x by simplifying both sides of the equation, then isolating the variable
x is equal to y/12

Answer 2

As the previous answer said, you can solve for x in the equation by simplifying and solving.
Starting with y=4x+8x
Simplify by adding like terms (4x and 8x)
y=12x
And divide by 12 on both sides to isolate the x

`(y)/(12) =x`
Would be your answer
