HOW TO CHANGE AN EQUATION SO IT HAS NO FRACTIONS

Multiply everything by the common denominator of the fractions.

HOW TO CHANGE AN EQUATION SO IT HAS NO DECIMALSMultiply each number by 10, 100, or 1000, … so there are no numbers behind a decimal.

0.3y = 2 – 0.8x 1.1x = 3y – 0.4

4 STEPS TO SOLVE A SYSTEM BY SUBSTITUTION

1. Solve one of the equations for one of its variables. 2. Substitute the expression from step 1 into the other equation and solve.

3. Substitute the value from step 2 into the equation form step 1 and solve.

4. Check the solution in each of the original equations.
