Answer:
Step-by-step explanation:
y = 1/8x - 1.....sub this back in for y in the other equation
-5x + 4y = -13
-5x + 4(1/8x - 1) = -13
-5x + 1/2x - 4 = -13.....multiple everything by 2 to get rid of the fraction
-5x(2) + 1/2x(2) - 4(2) = -13(2)
-10x + 1x - 8 = - 26
- 9x = -26 + 8
-9x = - 18
x = 18/9
x = 2.....now sub 2 in for x in either of the original equations to find y
y = 1/8x - 1
y = 1/8(2) - 1
y = 1/4 - 4/4
y = -3/4
so ur solution is : (2,-3/4) <===
