Question

Solve the equation 3x + 5y = 15 for y

Answer 1

3x + 5y = 15 / - 3x

5y = 15 - 3x / ÷ 5

y = 3 - 3/5x

:)

Answer 2

We are given this equation :

$3x + 5y =15$

We have to solve it for y, so we need to isolate y on the left side,

first we have 3x on the left side in addition, so when we take it to the right side we apply opposite operation that is subtract 3x

$5y =15-3x$

Next y is in multiplication with 5, so we apply opposite operation of multiplication that is division, so dividing right side by 5

$y=\frac{15-3x}{5}$
