Question

4y = 42 - 3y

Can you help me find y?

Answer 1

Bring all the variables with y to one side:
4y = 42 - 3y
4y + 3y = 42 - 3y + 3y
7y = 42

Divide both sides by 7 to get the y alone:
7y ÷ 7 = 42 ÷ 7
y = 6

Answer 2

4y = 42 - 3y

First, add '3y' to both of the sides.

`4y + 3y = 42`
Second, add '4y + 3y' to get '7y'.

`7y = 42`
Third, divide both sides by '7'.

`y = (42)/(7)`
Fourth, how many times does 7 go into 42? 42 ÷ 7 = '6'.

`y = 6`

Answer: y = 6
