Question

2. 3x = у у= 2х + 2 2​

Answer 1

Explanation:

3x = y

y = 2x + 22

3x = 2x + 22

3x -2x = 22

x = 22

3x22 = y

66=y

Answer 2

Explanation:

3x = y ------------(I)

y = 2x + 22 ---------------(II)

Substitute y = 2x + 22 in equation (I)

3x = 2x + 22 {Subtract 2x form both sides}

3x -2x = 22

x = 22

Plugin x = 22 in equation (I)

3*22 = y

y = 66
