Simplification of Algebraic Expressions

Simplify the following expression.

-3 + 5x + 8 + 2x

• 5 + 7x

• 5 - 7x

• -5 + 7x

• -5 - 7x

Combine like terms. Simplify. 
11g-9g+8g

• 10g

• 9g

• 2g

• 11g

Simplify (−3x − 2y) + (5y − 2x).

• x + 3y

• −5x − 3y

• −5x + 3y

• −x + 7y

Adding 2x + 3y to 4y + 3x gives

Combine like terms. Simplify.
3n – 6mn + 2n

• 3n-6mn

• 5n-6mn

• 5n+6mn

• n-6mn

7a + 5b - 2a - 4b

• 9a + b

• 5a + b

• 11a + 5b

• -9a - 9b

12a - 4b -7a + 2b

• 14a +5b

• 5a - 2b

• 7a - 5b

• 12a - 4b

Which expression is equivalent to:
d + d + d + 3 + 2

• 3d + 5
