Question

12 - 3x = -6x
I’m confused on how to solve for X if they are on both sides

Answer 1

x =-4

Explanation:

`12 - 3x = -6x`

Step 1 ; Collect like terms . (put the numbers with variables on one side of the equation and ordinary numbers on the other side )

`12 =-6x+3x`

Note ; When a number is crossing over an equality sign ; the sign will always change

Step 2 ;

Simplify

`-6x +3x =-3x\\\\ 12=-3x`

Step 3 ; Divide both sides of the equation by -3

`(12)/(-3) = (-3x)/(-3) \\\\-4 = x`

Switch sides

`x =-4`
