You have to move the 2a to the other side. It's added to -5d, so what operation do you have to use?
subtraction?

right. so what do will you have after subtracting 2a from both sides of the equation?
do i subtract 2a from 5d or 30?
From the 30. It helps to line up like terms so you can see what cancel. |dw:1443035502144:dw|
a - 5d = 28a ? sorry I'm terrible at this :/
no worries. You can only combine terms with the same variable (aka like terms). So on the right side, you can't subtract 2 from the 30 because the 2 has an \(a\) and the 30 does not. So when you subtract, it's going to stay \(30-2a\). On the left side, you have two like terms \(2a\) and \(-2a\). When you subtract them you get \(0\). In the same way that \(2 - 2 = 0\), when you put variable there \(2a-2a=0\)|dw:1443036063501:dw|
so now all that's left is to divide by -5 because it's mulitplied by d.
