Three supplementary angles are ∠ABC=(x−6)°, ∠CBD=(4x−14)°, and ∠DBE=5x°. What is the equation to solve for x?

Question

DO IT CORRECTLY.

Answer 1

x - 6 + 4x - 14 + 5x = 180

9x = 180 + 20

9x = 200

x = 200/9

x = 22.22

Answer 2

The bot correctly states the opening equation, but then
unexplainably cannot solve this grade 7 style equation.

x - 6 + 4x - 14 + 5x = 180
10x = 180 + 20
10x = 200
x = 20
