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

• 5x - 2y

• -x + y

• 2x - 3y

• -4x + 2y

Evaluate the expression when x = 5 and y = 2: 2x + 3y

• 14

• 25

• 7

• 10

Combine like terms in the expression: 4a + 2b - 3a + 5b

• 4a - 2b

• a + 7b

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

• 2x + 5y

• 3x - 2y

• 8x + 2y

• 7xy

Evaluate the expression when x = 7 and y = 1: 4x - 2y

• 4x - 2y = 4(7) - 2 = 26

• 4x - 2y = 4(7) - 2(1) = 30

• 28 - 2 = 26

• 4x - 2y = 4 - 2(1) = 2
