Answer:
2x+2y=-4
since we don't know the value of the letters, we could ignore it. then we add 2+2 which equals 4
6x-2y=12
In this case this equation is incorrect.
Step-by-step explanation:
sorry if I'm incorrect
(please if I'm correct, I really need the brainliest)
<span>5x−y=8 ; y = 5x - 8
7x+4y=22
substitute </span>y = 5x - 8 into 7x+4y=22
7x+4y=22
7x+4(5x - 8) = 22
7x + 20x - 32 = 22
27x = 54
x = 2
y = 5x - 8
y = 5(2)- 8
y = 10 - 8
y = 2
answer: x = 2 y = 2 or (2,2)
Answer:
False
Step-by-step explanation
Let's take the example starting number as 100

25% off of 85 is 63.45
40% off of 100 would be 60.
