Question

How do you solve for y in `5x+6y=90`?

Answer 1

`y=-5/6x+15`

Explanation:

`5x+6y=90`

Subtract `5x` from both sides of the equation.

`6y=90-5x`

Divide both sides by `6`.

`y=90/6-5/6x`

Simplify `90/6` to `15`.

`y=15-5/6x`

Rearrange terms on right side.

`y=-5/6x+15`

This the slope-intercept form of a linear equation `y=mx+b`, where `m` is the slope `-5/6` and `b` is the y-intercept `15`.
