Question

which equation can be used to solve for x? 6x - 4 = 68 6x + 64 = 90 2x = 68 6x - 72 = 180

Explanation:

Step1: Identify vertical - angles property

Vertical angles are equal. The angle measuring $68^{\circ}$ and the angle measuring $(6x - 4)^{\circ}$ are vertical angles.

Step2: Set up the equation

Since vertical angles are equal, we set up the equation $6x-4 = 68$.

Answer:

$6x - 4=68$
