Medal to the helper!

Which is an appropriate first step to solve the following equation for y? z= 2/3(x+y)

a. add the additive inverse of x to both sides
b. add the additive inverse of 2/3 to both sides
c. multiply both sides by the multiplicative inverse of z
d. multiply both side by the multiplicative inverse of 2/3

Answer 1

do you have a guess ?

Answer 2

Not really

Answer 3

so it is d
because then you will have only x and y on the right side

Answer 4

I see. Thank you so much :)
