Answer 2

What can you do to get y by itself?

Answer 3

2.8/2=Y
1.4=Y

Answer 4

Divide By 2

Answer 5

Correct. So what's 2.8 divided by 2?

Answer 6

1.4

Answer 7

Move all terms containing y to the left, all other terms to the right.

Add '-2y' to each side of the equation.
2.8 + -2y = 2y + -2y

Combine like terms: 2y + -2y = 0
2.8 + -2y = 0

Add '-2.8' to each side of the equation.
2.8 + -2.8 + -2y = 0 + -2.8

Combine like terms: 2.8 + -2.8 = 0.0
0.0 + -2y = 0 + -2.8
-2y = 0 + -2.8

Combine like terms: 0 + -2.8 = -2.8
-2y = -2.8

Divide each side by '-2'.
y = 1.4

Simplifying
y = 1.4

Answer 8

Correct. So y = 1.4. How to check your work?
y = 1.4
2y = 2.8
To get another y, you times both side by 2.
Therefore, your answer is correct!
I hope this help!

Answer 12

Okay Thank You

Answer 13

So -9= r/4 so i was thing would r be -36

Answer 14

\[\large \large -9= \frac{ r }{ 4 }\] To solve for r, you want to multiply. (Since it's the opposite of division)
So -9 * 4 = -36.
Therefore, your equation should look like: \[\large \large r = -9\times4\]
So you're correct. :)
