Answer:
8 + 9x
Step-by-step explanation:
This is an algebraic expression. Our job here is to simplify it by combining like terms: combine the x terms and then combine the constants:
-3x + 5 ¾ + 12x - 2.25, after combining the x terms, is
5 ¾ + 9x - 2.25
Next, combine the constants. It's easier to convert -2.25 to -2 1/4 and then
add this 2 1/4 to 5 3/4:
8 + 9x
