Question

Determine the value of y in the proportion 6y−10/5+7y =12 .

Select one:
A. 2
B. 5
C. 7
D. 10

Answer 1

its none of them? 6y - 10/5 +7y = 12 10 divided by 5 equals 2

it will now look like this: 6y - 2 + 7y = 12

then your going to want to add 2 to both sides of the equation.

it will now look like this: 6y -2 + 7y + 2 = 12 + 2 = 14

simplify: 6y + 7y = 14

add the like terms: 13y = 14
