Question

What is y variable?

2x - 3y = 9

x = 2y + 2

Answer 1

• The value of y is 5.

Explanation:

• => 2x - 3y = 9

x = 2y + 2

• => 2x - 3y = 9

2y + 2 = x

• => 2x - 3y = 9

-x + 2y = -2

• => 2x - 3y = 9

2(-x + 2y) = 2(-2)

• => 2x - 3y = 9

-2x + 4y) = -4

• => y = 5

Hence, the value of y is 5.

Answer 2

x = 12, y = 5

Explanation:

2x - 3y = 9

x = 2y + 2

Substitute x = 2y + 2,

2(2y+2) - 3y = 9

Simplify,

y + 4 = 9

y = 5

Substitute y = 5,

x = 2(5) + 2

Simplify,

x = 12
