Simplify the expression: 3x + 2y - 4x + 5y

• 2x + 7y

• -x + 3y

• -2x + 3y

• -x + 7y

Solve for x: 2x + 7 = 15

• x = 6

• x = 5

• x = 4

• x = 10

Evaluate the expression for x = 4 and y = 2: 3x + 2y

• 20

• 10

• 14

• 16

Find the value of y: 5y - 8 = 22

• y = 8

• y = 4

• y = 10

• y = 6

Simplify the expression: 4(2x + 3) - 2(3x - 5)

• 6x + 22

• 8x - 7

• 10x + 12

• 2x + 22

Solve for x: 3(x + 4) = 21

• x = 8

• x = 5

• x = 3

• x = 6

Evaluate the expression for x = 6 and y = 3: 2x - 5y

• 15

• 10

• -1

• -3

Find the value of x: 4x - 7 = 25

• x = 6

• x = 10

• x = 12

• x = 8

Solve for x: 5(x - 2) = 25

• x = 5

• x = 10

• x = 3

• x = 7
