+23251 To solve an equation do the opposite to the number that you want to remove.
You want to remove the 2; since it represents division, multiply both sides by 2:
2 · 24 = 2 · -r / 2
48 = - r
Now, to remove the negative sign, which represents multiplying by -1, divide by -1:
48 / -1 = -r / -1
-48 = r
