Question

5y + 2 =32

Answer 1

Just isolate the variable and divide by 5.

Answer 2

What does isolate mean?

Answer 3

Make it so that the 5y is alone on one side first, then get rid of the 5 of by dividing everything by 5.

Answer 4

2 + -2 + 5y = 32 + -2
2 + -2 = 0
0 + 5y = 32 + -2
5y = 32 +32 + -2 = 30
5y = 30 -2
Divide each side by '5'.
y = 6

Answer 5

Well I was hoping to let him do it, but I guess that's fine.

Answer 6

Nope I don't get it sorry:l thanks

Answer 7

Okay let's start from the beginning. This is an equation, meaning both sides are equal.

Answer 8

We want to find what y is, so to do that we need to get it alone on one side by doing whatever is necessary. But remember that what you do to one side you must do to the other.

Answer 9

So what is on the side with 5y in the original problem?

Answer 10

2

Answer 11

Yep, so what could you do to get rid of that 2?

Answer 12

I don't know:(

Answer 13

You could subtract 2 from both sides right? That wouldn't technically change the fact that the equation is still accurate, but it would get rid of the 2.

Answer 14

It's like having:

30=30
And subtracting 2 from both sides
28=28

The equation is still true

Answer 15

Does that make sense?

Answer 16

That would be 5y subtract 2 is 3

Answer 17

2 - 2 = 0
