Question

4x = 12x + 32 ? plz help me

Answer 1

Steps:

1) We have to keep the $x$'s on one side. For simplification can only occur between $x$ with each other.

2) We have to keep the number on other side. Be careful that you do not simplify it with the $x$.

Simply, group the like terms and simplify.

Methods:

$4x=12x+32$

=> $4x-12x=12x-12x+32$

=> $-8x = 0+32$

=> $-8x=32$

=> $\frac{-8x}{-8} = -\frac{32}{8}$

=> $x=-4$

or, (do side changing)

$4x=12x+32$

=> $4x-12x=32$

=> $-8x=32$

=> $x= \frac{32}{-8}$

=> $x=-4$

HOPE THAT HELPS YOU!! :-)))

Answer 2

We need to put all the xs on one side. We can always move an expression to the other side if we change the sign:

4x-12x=32

now we add up:

-8x=32

divide by 8:

-x=4

multiply by -1:

x=-4, which is the solution
