Identify Equation: Identify the equation to solve. We have the equation 15 = x + 5. We need to find the value of x.Isolate Variable: Isolate the variable x. To isolate x, we need to subtract 5 from both sides of the equation. 15 - 5 = x + 5 - 5Perform Subtraction: Perform the subtraction. Subtracting 5 from both sides gives us: 10 = xCheck Solution: Check the solution. We can check our solution by substituting x back into the original equation: 15 = 10 + 5 15 = 15 Since both sides are equal, our solution is correct.
