Question

Solve the equation for x.
√x+5 -1 = 2

Answer 1

Explanation:

Equation

√(x + 5) - 1 = 2 I take it that you want the 5 to be with the x.

Solution

√(x + 5) - 1 = 2 Add 1 to both sides

√(x + 5) - 1 +1 = 2 + 1 Combine

√(x + 5) = 3 Square both sides

√(x + 5)² = 3² Combine

x + 5 = 9 Subtract 5 from both sides

x + 5- 5 = 9- 5

x = 4

Answer x = 4
