Solve xy+7=n for y please hel

y = (n - 7)/x.

Step-by-step explanation: xy + 7 = n  The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 7.

xy = n - 7  Divide by x.

y = n/x - 7/x = (n - 7)/x

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70
