Answer:

x = 1.5

Step-by-step explanation:

Since they are corresponding angles, they equal to themselves

8x + 13 = 12x + 7

Subtract 12x from both side

-4x + 13 = 7

Subtract 13 from both side

-4x = -6

Divide by -4

x = 1.5

Answer:

20x=20

Step-by-step explanation:

8x+13+12x+7

(8x+12x)+(13+7)

20x+20
