Question

-3a+4+5a-7+a

Which of the following is equivalent to the expression?

Answer 1

To simplify the expression \(-3a + 4 + 5a - 7 + a\), we can combine like terms.

1. Combine the \(a\) terms: \(-3a + 5a + a = (5a - 3a + a) = 3a\)

2. Combine the constant terms: \(4 - 7 = -3\)

Putting it all together, we have:

\[ 3a - 3 \]

So the expression \(-3a + 4 + 5a - 7 + a\) is equivalent to \(3a - 3\).
