Answer:
x = 23
Step-by-step explanation:
(x + 1)° and (7x - 5)° are same-side supplementary angles, so adding them together will equal 180°.
(x + 1) + (7x - 5) = 180
Add like terms.
8x - 4 = 180
Add 4 to both sides.
8x = 184
Divide both sides by 8.
x = 23
Check if correct by substitution:
(23) + 1 = 24
7(23) - 5 = 156
156 + 24 = 180
I hope this helped you a lot! :)
