Explanation:
substitute y=3x-11 into 4x+5y=-17
4x+5(3x-11)=-17
4x+15x-55=-17
19x-55=-17
19x=-17+55
19x=38
x=-38/19
x=2
substitute x=2 into y=3x-11
y=3(2)-11
y=-6-11
y=-5
Answer:
4x + 5y = -17
we know if y = 3x - 11, so :
4x + 5(3x - 11) = -17
4x + 15x - 55 = -17
19x = -17 + 55
19x = 38
x = 2
y = 3x - 11
y = 3(2) - 11
y = 6 - 11
y = -5
So the answer is
and
