Question

write an equivalent expression with the fewest possible terms. now, write an equivalent expression with the fewest possible terms. $3a + 1b - 2a + 4b$ $= 3a + 1b + -2a + 4b$ $= 3a + -2a + 1b + 4b$ $= \square$

Explanation:

Step1: Combine like terms for $a$

$3a - 2a = (3-2)a = a$

Step2: Combine like terms for $b$

$1b + 4b = (1+4)b = 5b$

Step3: Sum the simplified terms

$a + 5b$

Answer:

$a + 5b$
