Question

Solve the equation for y7x + 4y = 8

Answer 1

To solve the equation for a variable we need to isolate the variable on the left side of the equation. The expression is:

`7x+4y=8`

To start we need to subtract by "7x" on both sides of the equation.

`\begin{gathered} 7x+4y-7x=8-7x \\ 4y=8-7x \end{gathered}`

We then need to divide both sides by 4.

`\begin{gathered} (4y)/(4)=(8-7x)/(4) \\ y=(8-7x)/(4) \end{gathered}`
