(3x+20)°+(5x−16)°=180° solve for x

x = 22

Step-by-step explanation:

(3x + 20) + (5x - 16) = 180

remove parentheses: (a) = a

3x + 20 + 5x - 16 = 180

group like terms

3x + 5x + 20 - 16 = 180

add similar elements: 3x + 5x = 8x

8x + 20 - 16 = 180

add/subtract the numbers: 20 - 16 = 4

8x + 4 = 180

subtract 4 from both sides

8x + 4 - 4 = 180 - 4

simplify

8x = 176

divide both sides by 8

8x/8 = 176/8

simplify

x = 22
