Hi! I was wondering how to do this! Thank you so much! y is equal to 3 times a number minus 2. If the output is 4, what is the input?

Answer 1

y= 3(x-2)

4=3x-6

3x =10

x = 10/3

unless you meant

y = 3x -2

4 =3x-2

3x = 6

x =2

3 times a number minus 2 is a little ambiguous, it could mean 3(x-2) or 3x-2
