SOLUTION: i need to solve the linear system using using substitution and elimination 4x-y=5 and 4x+4y=-4. also graph the linear equation and complete the table 4x-y=5 4x+4y=-4 x,

Question 879200: i need to solve the linear system using using substitution and elimination 4x-y=5 and 4x+4y=-4.
also graph the linear equation and complete the table
4x-y=5 4x+4y=-4
x,y x,y
0, 0,
1, 1
3, -1
and explain how the graph shows reasonableness of solutions of substitution and elimination
Answer by ewatrrr(24785) (Show Source): You can put this solution on YOUR website!
4x - y = 5
4x + 4y = -4 (time -1 and ADD EQs)
-5y = 9
y = -9/5 = -1.8 and x = .8
Ordered pair (.8, -1.8) the solution for this system
