Write and then solve the equation for the following. Please correct me if I'm wrong!!

1. If 3x+2x is equal to 15, what is the value of x?
Answer: x=3

2. If three times the quantity (4y-2) is equal to 18, what is the value of y?
Answer: y=1

  • Algebra -

    #1 correct
    #2
    If y=1, 4y-2=2 and 3*2 is not 18

    You should have done

    3(4y-2) = 18
    4y-2 = 6
    4y = 8
    y = 2
