Answer:

x=11

Step-by-step explanation:

For Problem 43:

Since 12x-18 and 5x+59 are vertical you set them equal to each other and solve:

12x-18=5x+59

Answer:

x=16 degrees

x=11 degrees

Step-by-step explanation:

Start with the equation: 4x-25=2x+7

Subtract 2 x's from each side: 2x-25=7

Add 25 to each side: 2x=32

Divide each side by 2 to get: x=16 degrees

Start with the equation: 12x-18=5x+59

Subtract 5 x's from each side: 7x-18=59

Add 18 to each side: 7x=77

Divide each side by 7 to get: x=11 degrees
