Question

3(a + b) - 2a - 2b

simplify the algebraic expression

Answer 1

You’d distribute the 3 to both a and b, which = 3a + 3b - 2a -2b, which would then = a + b. So a + b is the answer

Answer 2

a + b

Explanation:

3(a + b) - 2a - 2b

open the parenthesis

3 * a + 3 * b - 2a -2b

3a + 3b - 2a - 2b

combine like terms

3a - 2a + 3b - 2b

a + b
