I'll do the first one to get you started.


5%2Asqrt%28x%2B1%29=3 Start with the given equation.


sqrt%28x%2B1%29=3%2F5 Divide both sides by 5.


x%2B1=%283%2F5%29%5E2 Square both sides.


x%2B1=9%2F25 Square 3%2F5 to get 9%2F25


x=9%2F25-1 Subtract 1 from both sides.


x=-16%2F25 Combine the fractions.


So the solution is x=-16%2F25 which approximates to x=-0.64
