y =-7 3/4 =-7.75

Explanation:

Notice that the y-term is negative.
Adding 8y to both sides will give a positive y term on the left.

40color(blue)(+8y)= -8ycolor(blue)(+8y)-22

Subtracting 40 from both sides will isolate the y-term.

40 color(red)(-40) +8y = -22 color(red)(-40)

8y = -62

y= -62/8 = -31/4

y = -7 3/4
