Question

If 3y - 7= 23, then y =

Answer 1

y=10

Explanation:

3y-7 =23

3y = 23+7 -move 7 over

3y=30 -add remaing

3y/3 =30/3 -divide 3

y=10 -answer

check work 3x10-7=23

Answer 2

y=10 is the value of y

Explanation:

The given equation is

3y - 7 =23 ..............................(i)

We have to find out the value of y from the equation (i)

Now the equation is

3y - 7 = 23

adding 7 on both sides of the equation

3y - 7 + 7 = 23 + 7

3y = 30

as we need the value of y so

Dividing both sides of the equation by 3

`(3y)/(3)=(30)/(3)`

which will lead us to

y = 10

so this is the value of y
