Question

Can someone solve or explain to me how to do this?

Answer 1

a) x=5

b) x=6

Explanation:

a)

3x+7=180-(10x-22)

3x+7=202-10x

13x=195

x=5

b)

11x-3=4x+39

7x=42

x=6

I am so sorry I forgot what the formula names are but these are the correct solutions. It has been a while since I've done Geometry.
