Question

Simplify 5(x - 2) + 3x
8x - 2
8x - 10
-7x

Answer 1

Hello there. So for this, you need to use the distributive property. do you remember what that is?

Answer 2

yeah

Answer 3

Great so do the distributive property on 5(x-2)

Ignore the +3x, we can add that in later.

Answer 4

so 5x-2

Answer 5

and then you would subrtact 3x from both sides

Answer 6

Almost. Remember that a*(b*c) = (a*b) + (a*c)
So for this question you did the first part...

Answer 7

8x-2

Answer 8

You also need to distribute the 5 to the 2.

Answer 9

5(x-2)
So 5 is the a
x is the b
and -2 is the c

(5*x) + (5 * -2)

Answer 10

What you should get is (5x) + (-10)

Answer 11

That's basically 5x - 10. Are you following so far?

Answer 12

yes

Answer 13

Cool so now all we have left is the +3x which was not part of the distribution. So 5x + 3x = 8x.

Our answer will be 8x - 10. Don't forget to distribute the second part.

Answer 14

ok thanks so much

Answer 15

Yup. good luck!
