To simplify the given expression, we need to combine like terms:
4a + 12 + 2a + 7 - 7a + 21 + a + 1
Combine the "a" terms:(4a + 2a - 7a + a) = 0
Combine the constant terms:(12 + 7 + 21 + 1) = 41
Thus, the simplified expression is:41
To simplify the given expression, we need to combine like terms:
4a + 12 + 2a + 7 - 7a + 21 + a + 1
Combine the "a" terms:
(4a + 2a - 7a + a) = 0
Combine the constant terms:
(12 + 7 + 21 + 1) = 41
Thus, the simplified expression is:
41
