Answer:
-10x + 7.5
Explanation:
In algebra, an important concept is combining like terms. Often, expressions will need to be rendered and combined, before they can be solved.
The distributive property says that if we multiply the outside number by both number in the the parentheses, we can obtain an equivalent expression.
-2.5 x 4 and -2.5 x -3
-10x + 7.5
