Given the numerical equation:
2x - 4(4x - 8) = -94
Solve for x.
Solution:
In order to solve for x, we first need to distribute -4 to each value inside the parenthesis.
2x - 4(4x - 8) = -94
2x - 16x + 32 = -94
Transpose 32 on the other side of the equation, hence we must take note that in transposing a number, the sign changes.
2x - 16x = -94 - 32
-18x = -126
Divide both sides by -18 to cancel out -18x, leaving behind x.
-18x/-18 = -126/-18
x = 7
Final answer:
x = 7
