Question

26-4s=9s solve the equation

Answer 1

s=2

Explanation:

We are given the equation:

`26-4s=9s`

and asked to solve. We want to find out what the unknown variable, s, is. Therefore, we must isolate s on one side of the equation.

First, let's get all the terms with s on one side of the equation. 4s is being subtracted from 26. The inverse of subtraction is addition. Add 4s to both sides of the equation.

`26-4s+4s=9s+4s`

`26=9s+4s`

`26=13s`

s is being multiplied by 13. The inverse of multiplication is division. Divide both sides of the equation by 13.

`26/13=13s/13`

`26/13=s`

`2=s`

`s=2`

Let's check our solution. Plug 2 in for s and solve.

26-4s=9s

26-4(2)=9(2)

26-8=18

18=18

This checks out, so we know our solution is correct.

The solution to the equation 26-4s=9s is s=2.

Answer 2

26=9s+4s

13s=26

s=26/13

s=2
