8y=2(3y-7) answer this equation

-10½

Step-by-step explanation:

8y = 2(3y-7)

first of all we open the bracket on the right hand side, so we have..

2(3y-7)= (2*3y) - (3*7)

= 6y-21

so,

8y = 6y-21

so, collecting like terms we have

8y-6y = 6y-6y-21

2y = -21

so dividing both sides by 2, we have:

2y/2= -21/2

y = -10½

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz
