Question

Solve the formula A=10+ry. solve for y

Answer 1

$y = - \frac{10}{r} + \frac{A}{r}$

Answer 2

The given formula $A= 10 + ry$

Solve for y means we have to make y alone

$A= 10 + ry$ \\

Add -10 on both sides, we get

$A - 10 = 10 -10 + ry \\A - 10 = 0 + ryA - 10 = ry$

As there is multiplication sign between r and y so to solve for y, divide both side by r

$\frac{A - 10}{r} = y\\\\y = \frac{A - 10}{r}$
