Solve for x, then find measure of each angle 1st angle (7x-7) and 2nd angle [2(3x+3)]

(7x -7) + (6x +6) = 90

take away the parenthesis: 7x - 7 + 6x + 6 = 90

combine like terms: 13x - 1 = 90

add 1 to both sides: 13x = 91

divide both sides by 13: x = 7.

Now: substitute x = 7 into the angles: the first angle is 42 degrees, the second angle is 48 degrees

Idk i am in 5th grade lol
