Question

solving equations with variables on both sides
how do u solve 2r-(5-r)=13+2r

Answer 1

The way to begin is to "collect" terms together... get the "r" terms together and the number terms together:

2r - (5-r) = 13 + 2r

2r -5 + r = 13 + 2r
3r - 5 = 13 + 2r

So now the original expression is simplified somewhat.

Next, you need to get all the r terms on one side and the numbers on the other.

Answer 2

do u divide
