45 = 2x - 5

50 = 2x

divide both sides by 2

25 = x

the value of x is 5

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:

x = -7

Step-by-step explanation:

To find the value of x, you need to set up a proportion:

$\frac{x-2}{15}$ = $\frac{x-1}{18}$

Then cross multiply:

15x - 15 = 18x + 36

Then subtract 15x from both sides:

-15 = 3x + 36

Subtract 36 from both sides:

-51 = 3x

Finally, divide both sides by 3:

x = -7
