2.20x + 2.95y <= 10
x+y = 4
Step-by-step explanation:
Answer:
9/2
Step-by-step explanation:
4.5 = 4 1/2 = 9/2
Get y alone
so
-8y=13-7x (by subtracting 7x from both sides)
now you still want y by itself so you divide by -8
leaving you with
y=-13/8 + 7/8
Rx - st = r
Rx = r + st Add st to both sides
Rx - r = st Subtract r from both sides
(Rx - r)/t = s Divide t on both sides ( to isolate s)
