Answer:
B, because first of all, y = 4x + 6, so you could cross off A. It can't be C either because there are 4x, not 4y. And it can't be D because Y is also 6 more. If it was 6 more, 4x - y would be a negative number since y is more than 4x.
Step-by-step explanation:
i)
2(x+2)=7
2x+4=7
2x=7-4
2x=3
x=3/2
ii)3x + y =8 , y=x
3x + x = 8
4x = 8
x = 2
43.75 was the original price of the laptop bag
according to question
X of 80% = 35
X x 80/100 = 35
X = (35x 100)/80
X = 43.75 dollars
-x + 10
(x + 7) - (2x-3)
x + 7 - 2x - 3
x - 2x
-x + 7 + 3
