Solve each system of linear equations by substitution. Show all your work/steps. List your solution as a point for each system (x, y) and check your answers against each equation. Example: Solve the system of equations: x + y 8 and y - 3x x+y =8 y = 3x Solution (2, 6) Check x +y =8 y- 3x x+ 3x -8 y = 3(2) 2 +6 =8 6 = 3(2) 4x =8 y =6 8 = 8 6 =6 4x/4 = 8/4 L=R L-R x= 2
