Question

How do you solve the multi-step equation `29-3s=23(2s-3`)?

Answer 1

See the steps below, which I used to solve this equation and find that `s=2`.

Explanation:

`29−3s=23(2s−3)`

First expand the brackets:

`29−3s=46s-69`

Now collect like terms - all terms in `s` on the left and all number-only terms on the right. We do this by subtracting `29` from both sides and subtracting `46s` from both sides:

`-49s=-98`

Now divide both sides by `-49`

`s=(-98)/(-49)=2`
