What value of x makes the equation true 9.68x + 21.6 - 6.23x=2.3x+17

9.68x + 21.6 - 6.23x = 2.3x + 17

Combine like terms on the left side:

3.45x + 21.6 = 2.3x + 17

Subtract 2.3x from both sides:

1.15x + 21.6 = 17

Subtract 21.6 from both sides:

1.15x = -4.6

Divide both sides by 1.15:

X = -4

i believe the answer is c.

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
