Jackson is given the expression below to simplify.

Question

9x - 4 + 4x + 5x + 19

which expression is equivalent to Jackson expression

Answer 1

To simplify the expression \( 9x - 4 + 4x + 5x + 19 \), we can combine like terms.

1. First, combine the \( x \) terms:

\[ 9x + 4x + 5x = (9 + 4 + 5)x = 18x \]

2. Next, combine the constant terms:

\[ -4 + 19 = 15 \]

Putting it all together, the simplified expression is:

\[ 18x + 15 \]

Thus, the equivalent expression to Jackson's expression is \( 18x + 15 \).
