Question

In a recent golf match,Tigers score was 4 less than Phil's score. Their combined scores totaled 140. Let p represent Phil's score and t represent Tiger's score?

Answer 1

We have two equations here:

Explanation:

`t=p-4`
`t+p=140`

We may replace `t` in the second equation by `p-4`
`p-4+p=140->`

Now add `4` to both sides:
`p-cancel4+p+cancel4=140+4->`
`2p=144->p=72->`
`t=p-4=72-4=68`

Check : `t+p=68+72=140`
