1. Solve each system by graphing. Include all of the points on the graph.
a) 3x-2y =6
3x =2y =6
b) 3y -3x =9
x-y=1
c) 4x - 5y =-2
3y-x=3
4) y= x + 4
3y-5x=6
2. Solve each system by substitution. Determine whether the equations are independent , dependent or inconsistent.
a)2x-y-3
2Y=4X-6
b) Y=3(X-4)
3X-y=12
3) Solve the equation using the substitution method.
a) 6x-3y=3
10x=y+7
4) Write a system of two equations with two unknowns for the problem. Solve the system by substitution.
