Step-by-Step Solution to Solve 68 = -52x + 16
The process of solving this equation can be broken down into systematic steps:
Step 1: Subtract 16 from both sides
This removes the constant term on the right side, simplifying the equation:
68 - 16 = -52x + 16 - 16
Which simplifies to:
52 = -52x
Step 2: Divide both sides by -52
To solve for x, divide both sides of the equation by the coefficient of x:
(52) / (-52) = (-52x) / (-52)
This yields:
-1 = x
Alternatively, you can write:
x = -1
Final answer: x = -1

Verifying the Solution
It’s always good practice to verify your solution by substituting the value of x back into the original equation:
Original equation: 68 = -52x + 16
Substitute x = -1:
68 = -52 (-1) + 16
Calculate:
68 = 52 + 16
Simplify:
68 = 68
Since both sides are equal, the solution x = -1 is verified and correct.
