Question

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

Answer 1

y = (-8)/9

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

Answer 2

-8/9

Explanation:

2 x − 9 y = 22

x=7

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