You can solve for the variable by using the Properties of Equality.

25.7

Practice makes perfect

To solve the proportion, we will start by using the Properties of Equality in order to isolate the variable. Then we will simplify the obtained expression.

2.14=x/12

LHS * 12=RHS* 12

2.14* 12=x

Multiply

25.68=x

Rearrange equation

x=25.68
