Question

Solve the following equations for the given variable.

7x+5y=8 for x

Explanations help!

Answer 1

5y+7x-7x=8-7x

5y=8-7x

5y/5 = (8-7x)/5

y = (8-7x)/5

Explanation:

Answer 2

`x = - (5)/(7) y + 1 (1)/(7)`

Explanation:

`7x + 5y = 8`

-5y on both sides:

`7x = - 5y + 8`

Divide both sides by 7:

`x = - (5)/(7) y + (8)/(7)`

`x = - (5)/(7) x + 1 (1)/(7)`
