(x + 7) equal to 15.5 and -15.5.

Subproblem 1

x + 7 = 15.5 Simplifying x + 7 = 15.5 Reorder the terms: 7 + x = 15.5 Solving 7 + x = 15.5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = 15.5 + -7 Combine like terms: 7 + -7 = 0 0 + x = 15.5 + -7 x = 15.5 + -7 Combine like terms: 15.5 + -7 = 8.5 x = 8.5 Simplifying x = 8.5

Subproblem 2

x + 7 = -15.5 Simplifying x + 7 = -15.5 Reorder the terms: 7 + x = -15.5 Solving 7 + x = -15.5 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + x = -15.5 + -7 Combine like terms: 7 + -7 = 0 0 + x = -15.5 + -7 x = -15.5 + -7 Combine like terms: -15.5 + -7 = -22.5 x = -22.5 Simplifying x = -22.5

Solution

The solution to the problem is based on the solutions from the subproblems. x = {8.5, -22.5}
