Simplify each equation using PEMDAS:
Parentheses (x)
Exponents x²
Multiplication and Division, left to right × ÷
Addition and Subtraction, left to right - +
It is also important to follow PEMDAS when working within grouping symbols like parentheses.
Also, remember that two negatives make a positive, and when a negative and positive are multiplied, the result is always negative.

Answer:
x = 12
Step-by-step explanation:
In a pair of intersecting lines the vertically opposite angles are equal.
(6x + 7)° = (8x - 17)°
6x + 7 = 8x - 17
Subtract 8x + 7 from both sides:
6x + 7 - (8x + 7) = 8x - 17 - (8x + 7)
(6x - 8x) + (7 - 7) = (8x - 8x) + (-17 - 7)
6x - 8x = -2x:
-2x + (7 - 7) = (8x - 8x) + (-17 - 7)
7 - 7 = 0:
-2x = (8x - 8x) + (-17 - 7)
8x - 8x = 0:
-2x = -17 - 7
-17 - 7 = -24:
-2x = -24
Divide both sides by -2:
x = 12
