Question

Need help with Geometry homework.

Could someone please explain how to solve this equation and tell me how to solve problems like the equation?

Answer 1

Answer:

SU = 22

Step-by-step explanation:

SR = RU

4x - 1 = x + 8

3x - 1 = 8

3x = 9

x = 3

SR =  4(3) - 1 = 11

RU =  3 + 8 = 11

SU = 11 + 11 = 22
