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

x =-4

Step-by-step explanation:

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

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

Step 2 ;

Simplify

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

Switch sides

the image of (6, 9) under a dilation is (4, 6). the scale factor is

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
