Question

-3x + y = -2 IF x=-3 x=-1 x=2 what does y equal?

Answer 1

-11, -1, -8 that is all of what y would =

Answer 2

Value of y is -11, -5 and 4 respectively.

Explanation:

We have the equation,

`-3x + y = -2` i.e.
`y=-2+3x`.

Substituting the values given of 'x', we get,

For x= -3,
`y=-2+3* (-3)` i.e.
`y=-2-9` i.e. y= -11

For x= -1,
`y=-2+3* (-1)` i.e.
`y=-2-3` i.e. y= -5

For x= 2,
`y=-2+3* 2` i.e.
`y=-2+6` i.e. y= 4

Thus, the value of y is -11, -5 and 4 respectively.
