Exercise 3 Page 97

Gather all of the variable terms on one side of the equation and all of the constant terms on the other side.

Practice makes perfect

To solve an equation, we should first gather all of the variable terms on one side of the equation and all of the constant terms on the other side using the Properties of Equality. In this case, we will start by finding the least common denominator, so that we can add the fractions.

2m/7+3m/14=1

ExpandFrac

a/b=a * 2/b * 2

2m*2/7*2+3m/14=1

Multiply

4m/14+3m/14=1
