1

4

5

25

Answer 1

Distribute 3 first to (x-1)

Answer 2

i did is it 25 ?

Answer 3

thank you brinethery and katrina
i got more need help with so ima post them look out for them

Answer 4

i did thatbut is it 25 ?

Answer 5

Your first step is to always distribute: In this case, you have two terms to distribute:
3 to x + 1
-2 to x -1
It basically means:
3(x + 1) ---> (3 x 'x') + (3 x 1)
and
-2 (x - 1) ---> (-2 x 'x') - (-2) x (-1)

Answer 6

3x+3 = -2x +2 +6

Can you solve this?

Answer 7

no

Answer 8

Your goal for linear functions is to get all the constants to one side, and all variables to the other. Try it

Answer 10

im not asking yall to show me how to do it im just trying to check my answers

Answer 11

You told me that you didn't know how to solve this. 3x+3 = -2x +2 +6

Answer 12

You got 25 yes?

Answer 13

Patience is a virtue, is it not?

Answer 14

yes i got 25

Answer 15

@VRFGVD I know you don't like to hear this, but you need to learn how to solve for x before you start learning how to distribute stuff. It's all a stepping stone thing.

Answer 16

That is inaccurate Vrfgvd. Lets try again:
Can you start us off with the first step?

Answer 17

3x+3 = -2x +8

What do you do first?

I would subtract 3 from both sides.

Answer 18

And then add 2x to both sides.

Answer 19

so 10x

Answer 20

Why? Because remember, in a linear function, variables go on one side of the equal sign, and constants on the other.

Answer 21

divide that by 2 then it leaves 5

Answer 22

3x +3 -3 = -2x +8 -3

3x = -2x +5


3x +2x = -2x +2x +5

5x = 5

Answer 23

i need help with this one to please

Solve for x: −3(x + 3) = −3(x + 1) − 5

6

−6

All real numbers

No solution

Answer 24

Would you like to use twiddla to have a better understanding?

Answer 25

@VRFGVD what grade level is this for?
