Question

Solve for x

A) 12
B) 13
C) 10
D) 11

Answer 1

Answer: A)12

Explanation:

The line YZ must be half the size of the line QS, so double the length of YZ should be equivalent to the value of QS

2(x+2)=2x+4

Now we can set them equal to each other and solve for x

`2x+4=3x-8\\2x+4+8=3x-8+8\\2x+12=3x\\2x-2x+12=3x-2x\\12=x`
