Question

Solve the equation for y. Then find the value of y for each value of x.

y+5x=9;x= -2, 0, 4

Answer 1

When x = -2

`y+5\left(-2\right)=9`

`y-5\cdot \:2=9`

`y-10=9`

`y-10+10=9+10`

`y=19`

When x= 0

`y+5\left(0\right)=9`

`y+5\cdot \:0=9`

`y+0=9`

`y=9`

When x= 4

`y+5\left(4\right)=9`

`y+5\cdot \:4=9`

`y+20=9`

`y+20-20=9-20`

`y=-11`
