Question

5(a-1)-15=3(a+2)+4

Answer 1

alright start from simplifying
first Distribute and combine like terms

can you do that

Answer 2

ok do i subtract 5 from fifteen to get -10

Answer 3

The 5 on the left side is multiplying a - 1, so you can't combine it with the -15.
You need to start by using the distributive property on both sides
on 5(a - 1) and on 3(a + 2)

Answer 4

Do you know how to use the distributive property
to simplify 5(a - 1) and to simplify 3(a + 2)?

Answer 5

yes

Answer 6

ok now i h

Answer 7

have 5a-10=3a+10

Answer 8

5(a - 1) - 15 = 3(a + 2) + 4

5a - 5 - 15 = 3a + 6 + 4

Did you get this as your first step?

Answer 9

yeah

Answer 10

Now combine -5 -15 on the left side and combine 6 + 4 on the right side.

Answer 11

that was a negitive 5

Answer 12

It is -5 from distributing.

Answer 13

ok

Answer 14

do i add 3a to both sides next

Answer 15

\(5a \color{red}{- 5 - 15} = 3a + \color{red}{6 + 4}\)

Do the two red parts.
Just do the parts in red now.

Answer 16

5a-20=3a+10

Answer 17

Good.
Way above you had -10, not -20, on the left side.
Now it's correct.

Answer 18

We want all a's on the left side, and all numbers on the right side.
Now subtract 3a from both sides.

Answer 19

2a-20=10
