Hi there
7y = 8y + 2
Combine like term
7y - 8y = 2
-y = 2
Divide both sides by -1
-y/-1 = 2/-1
Y= -2

Hi there!
Angles in a triangle sum up to 180°, so:
180° = 110° + 5x° + 2x°
Simplify:
180° = 110° + 7x°
Subtract both sides by 110:
70° = 7x°
Divide both sides by 7:
x = 10°
Plug in to solve for the other angles:
5x = 5(10) = 50°
2x = 2(2) = 20°
