Linear Combination

Definition: System of Linear

Equations

Two or more linear equations involving the same variables

STEP 1

Rearrange each equation so the variables are on one side (in the same order) and the constant is on the other side.

STEP 2

Multiply one or both equations by an integer so that one term has equal and opposite coefficients in the two equations.

STEP 1

Rearrange each equation so the variables are on one side (in the same order) and the constant is on the other side.

STEP 2

Multiply one or both equations by an integer so that one term has equal and opposite coefficients in the two equations.

STEP 3

Add the two equations together so one variable is eliminated and solve the resulting equation.

STEP 4

Substitute the value of the first variable into either of the two original equations and solve for the second variable.
