To solve the equation |-5x + 7| = 42, we
need to consider two cases: when the expression inside the absolute value is
positive and when it is negative.
Case 1: -5x + 7 is positive
If -5x + 7 is positive, then the equation
becomes -5x + 7 = 42.
Solve for x:
-5x + 7 = 42
-5x + 7 - 7 = 42 - 7
-5x = 35
-5x/(-5) = 35/(-5)
x = -7
