Question

What is the value of x?

Answer 1

Answer: the value of x is 70

Steps:

the angles 45 and (2x-5) are supplementary, so they add up to 180 degrees. We use that property to solve for x:

2x-5 + 45 = 180

2x = 140

x=70

Answer 2

45 = 2x - 5

Add five to each side

50 = 2x

divide both sides by 2

25 = x

the value of x is 5
