Solve the following two-step linear equation. −3x+42=5

1 answer

To solve the equation −3x + 42 = 5, we need to isolate the variable x by following these steps:

Step 1: Subtract 42 from both sides of the equation:
−3x + 42 - 42 = 5 - 42
−3x = -37

Step 2: Divide both sides by -3 to solve for x:
x = -37 / -3
x = 37 / 3

Therefore, the solution to the equation −3x + 42 = 5 is x = 37 / 3.
