Simplifying Variable Expressions
Simplify each expression using the distributive property and combining like
terms.
1) 4 + 3x + 7
2) 6x + (-2x)
3) 3(-4x) + 3 – 5
4) 5a + 4a + 3a + 2a + a
5) 3(5t) – 2(2t)
6) 5z + 4y + 3z + 2y
7) 10(w + 2x) – 2(w – x)
8) (2t + 4)3 + 6(-5t) – (-8)
9) 5(4a – 2b + c) + 3(2a – 5b)
10) -2(4x + 2y) – 3(x + 2z) + 5(3y – 2z)
Simplify. Evaluate when x = 2, y = -5, and z = 8
11) 3x + 2x + y
12) -5x + 3y + 2z
113) z(2x + 3x)
