Question

6x-6y=23 find y when x=8

Answer 1

y= 4.166

If rounded to the nearest tenth

y = 4.2

Explanation:

6x - 6y = 23

x = 8

6x - 6y = 23 (Sub in the x with 8)

6(8) - 6y = 23

48 - 6y = 23 (Subtract each side by 48)

-6y = 23 - 48

-6y = -25 (Divide each side by -6)

y = 4.166

If rounded to the nearest tenth

y = 4.2
