Question

5x-5 = 3x-9?? solve

Answer 1

Get your x terms to the left side and your constant terms to the right side.

Answer 2

okay @gypsy1274 ??

Answer 3

Using inverse operations. If the term is positive, then subtract it from both sides. If the term is negative, then add it to both sides.

Answer 4

If you had:
\(2x+3=15\)
You would subtract 3 from both sides to get:
\(2x=12\)

Answer 5

okay @gypsy1274

Answer 6

What did you come up with?

Answer 7

8x =4??

Answer 8

Close.
\(5x-5=3x-9\)
The x terms in this equation are positive which means that you will need to subtract to get the \(+3x\) to the other side of the equation.
\(5x-3x=?\)

Answer 9

2z

Answer 10

2x?
So you now have:
\(2x-5=-9\)
What do you do next?

Answer 11

add 5 to get 2z = -4?? which will give x= -2

Answer 12

Yes. Except that you z should be an x. The variable name will make a bigger difference when you start working with more variables in the equation.
