Question

What is the solution to the equation?

3(x – 5) = 8x – 30

A.
x = 3

B.
x = 5

C.
x = –3

D.
x = –5

Answer 1

Distribute 3

3 * x = ?
3 * -5 = ?

Answer 2

what do you think it is first?

Answer 3

distribute 3 x "x" and 3x-5

Answer 4

Distributing gives us:

3x - 15 = 8x - 30

Add 15 to both sides -30 + 15 = ?

Answer 5

= 15

Answer 6

Yes, that gives us:

3x = 8x + 15

Now we subtract 8x to both sides, what's 3x - 8x?

Answer 7

-5x?

Answer 8

Answer 9

Can you help with one more?

Yep, now we have:

-5x = 15

Now we divide -5 to both sides, what's 15 / -5

Answer 11

And yes, I can
