Question

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

Answer 1

Answer:

x=−4

Step-by-step explanation:

12-3x=-6x

add -3x on both sides

12=-6x+3x

add -6x and 3x together

12=-3x

divide both sides with -3

$\frac{12}{-3}\frac{-3x}{-3}$

-4=x

since -3*4= -12

hope this makes sense

Answer 2

Answer:

x =-4

Step-by-step 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

$\frac{12}{-3} = \frac{-3x}{-3} \\\\-4 = x$

Switch sides

$x =-4$
