Ineed s much im sooo lost i will give a brainliest to the person who includes all work, correct answer, and everything makes sense. (variables on both sides of an equation) solve: 5(a-1)-15=3(a+2)+4

We start by using the distributive property to expand the terms  and . When we do, we obtain  and .

Putting those back into our equation, we have:



Next, we combine all of the constants on either side:



Finally, we want to get the variable a by itself on one side of the equation, so we perform the following steps to isolate it:

(Add 20 to both sides)
(Subtract 3a from both sides)
(Divide both sides by 2 to isolate a)

So, we obtain our answer of .

Subtracting is the opposite of adding
