5-29.

Solve the following equations for the given variable, if possible. Remember to check your answers.

$6x^2=150$
Hint (a):
Isolate the $x^2$ . There are two solutions to this equation.

$4m+3-m=3(m+1)$
Answer (b):
All numbers, because the expressions on both sides are the same $3m+3=3m+3$

$\sqrt{5x-1}=3$
Hint (c):
Start by squaring both sides.

$(k-4)^2=-3$
Answer (d):
No real numbers, because any number squared is a positive number, so $(k-4)^2\ne-3$ .
