Question

How do I solve 4(2x + 1)- 3 = -3(x - 4)?

Answer 1

You have to distribute out what's outside the parentheses first. Do you know how to do that?

Answer 2

No

Answer 3

Distributive Preoperty: \(a(b + c) = ab + ac\)

Answer 4

Oh wait yes.

Answer 5

That's basically means that the number outside of the parentheses you have to multiply it to everything inside the parentheses

Answer 6

I got 8x+4-3=-3x+12+12, is it right?

Answer 7

8x+4-3=-3x+12

You added an extra 12 on the right hand side

Answer 8

But other than that you are right. Think you can handle it from there?

Answer 9

Oh oops, lol.

Answer 10

Now what do I do?

Answer 11

You want all the x's to be on one side and all the numbers on the other side. Let's start by adding 3x to both sides. This will get rid of the -3x from the right hand side.

8x+4-3=-3x+12
8x+3x+4-3=-3x+3x+12
8x+3x+4-3=12
11x+4-3=12

Answer 12

From there you can simplify it even further by doing this 4-3?

Answer 13

Would the answer be 1, right?

Answer 14

Yeah you are right man Good job!

Answer 15

Thank you =)
