Answer:
Step-by-step explanation:
(x,y) (1,-1)
y=3-4x
-x+2y=-3
x+2(3-4x)=-3
x=1
y=3-4*1
y=-1
the answer is 9 bb ♡
57-36÷3×4
57-48=9
y = -4
-2x + 5y = 8
Let x=-14
-2(-14) +5y = 8
28 +5y = 8
Subtract 28 from each side
28-28 +5y = 8-28
5y = -20
Divide by 5
5y/5 = -20/5
Answer:61 and 39
62
Of means multiply and is means equals
.03 * n = 1.86
Divide each side by .03
