Given that 2 x - 9 y = 22 Find y when x = 7

y = (-8) / 9

Step-by-step explanation:

Solve for y:

14 - 9 y = 22

Subtract 14 from both sides:

(14 - 14) - 9 y = 22 - 14

14 - 14 = 0:

-9 y = 22 - 14

22 - 14 = 8:

-9 y = 8

Divide both sides of - 9 y = 8 by - 9:

(-9 y) / (-9) = 8 / (-9)

(-9) / (-9) = 1:

y = 8 / (-9)

Multiply numerator and denominator of 8 / (-9) by - 1:

Answer: y = (-8) / 9

-8/9

Step-by-step explanation:

2 x - 9 y = 22

x=7

2*7-9y=22 14-9y=22 9y=14-22 9y=-8 y = - 8/9
