Question

Solve the equation for y.7x + 4y = 16

Answer 1

Step-by-step explanation:

The first step in solving the equation for y is to subtract 7x from both sides. This gives

`7x+4y-7x=16-7x`

`\Rightarrow4y=16-7x`

finally, dividing both sides by 4 gives

`(4y)/(4)=(16-7x)/(4)`
`y=(16-7x)/(4)`

rewriting the right-hand side gives

`y=(16)/(4)-(7)/(4)x`
`\Rightarrow\boxed{y=4-(7)/(4)x}`

which is our answer!
