Answer:
2 solutions.
Step-by-step explanation:
Rearrange the second equation:
-8x - 4y = -20
-4y = 8x - 20
Divide through by -4:
y = -2x + 5
and our first equation is
y = 2x - 5
Subtracting the 2 equations
0 = -2x -2x + 5 -(-5)
0 = -4x + 10
x = 5/2
and y = 2(5/2) - 5 = 0.
5/4
2 1/2=5/2
(5/2)(1/2)=5/4
5
answer
