6-110.

Solve the following equations using any method. Show your work and check your solution.

1. $3x+10=25$

Subtract 10 from both sides.
$3x+10-10=25-10$

Divide both sides by $3$.

$x=5$

1. $5(x-2)=30$

Start by dividing both sides by $5$.

When you have found a solution, substitute it into the equation for $x$ to check your answer.

1. $2x-9=x+7$

Isolate $x$ on one side of the equation. When you have found an answer, be sure to check it.

$x=16$
