Question

What is -7/2y = 21/2 what is the solution_______? Brainliest is on the mark if 10 point will be added as well!

Answer 1

Answer:

y= -3

Step-by-step explanation:

(-7/2)y  =21/2

Divide both sides by (-7/2) = Multiply by (-2/7)

On the left side ,after cancellation you have only  y

On the right side you multiply 21/2 by (-2/7)

y= (21*-2) / 2*7

y=(-42)/14

y=(-21)/7

y=- 3    

check:

-(7/2) of- 3 is  10.5         21/2=10.5
