  1. 3. A system of equations is a set of one or more equations involving a number of variables. The solutions to systems of equations are the variable mappings such that all component equations
  2. 5. question x + 3y = 1 -3x - 3y = -15
  3. 6. To solve a system of linear equations graphically we graph both equations in the same coordinate system.
Down
  1. 1. question - 3y = -1 y = x - 1
  2. 2. solve one of the equations for either variable. Substitute the expression from Step 1 into the other equation. Solve the resulting equation.
  3. 4. any coefficients are fractions, clear them. Make the coefficients of one variable opposites. Decide which variable you will eliminate.
