Answer:
y = 7/2x -11/2
Step-by-step explanation:
7x-2y=11
Subtract 7x from each side
7x-2y -7x = -7x+11
-2y = -7x+11
Divide each side by -2
-2y/-2 = -7x/-2 +11/-2
y = 7/2x -11/2
Answer:
y = 7/2x - 11/2
Step-by-step explanation:
7x - 2y = 11
Subtract 7y to both sides
-2y = 11 - 7x
Divide -2 to both sides
y = 11/-2 - 7/-2x
Best of Luck!

Ba=ab+18
a+b=8, b=8-a
10b+a=10a+b+18
10b-b=10a-a+18
9b=9a+18
9(8-a)=9a+18
72-9a=9a+18
9a+9a=72-18

a=54:18
a=3
b=8-3
b=5
the number is 35
