Question

Substitute the known value of x​ into y=4x+20​. Then solve for y entering the equation in simplest form

Answer 1

`y=24,` when
`x=1`.

Explanation:

Given:
`y=4x+20`

To find: Value of
`y`, substituting the known value of
`x`

We have,

`y=4x+20 ...(i)`

Putting
`x=1` in equation
`(i)`, we get

`y=4(1)+20`

`\implies y=4+20`

`\implies y=24`

Hence, the value of
`y` is
`24`, when the value of
`x` is
`1`.
