Question 752498
Solve:
{{{-7+5sqrt(2x+3) = 8}}} First, add 7 to both sides of the equation.
{{{-7+7+5sqrt(2x+3) = 7+8}}} Simplify.
{{{5sqrt(2x+3) = 15}}} Now divide both sides by 5.
{{{(5sqrt(2x+3))/5 = 15/5}}} Divide.
{{{sqrt(2x+3) = 3}}} Square both sides.
{{{(sqrt(2x+3))^2 = 3^2}}} Evaluate.
{{{2x+3 = 9}}} Subtract 3 from both sides.
{{{2x+3-3 = 9-3}}} Evaluate.
{{{2x = 6}}} Finally, divide both sides by 2.
{{{x = 3}}}
