Question

How do you simplify `7a+3b-4a-5b`?

Answer 1

See a solution process below:

Explanation:

First, rewrite the expression by grouping like terms:

`7color(red)(a) - 4color(red)(a) + 3color(blue)(b) - 5color(blue)(b)`

Now, combine like terms:

`(7 - 4)color(red)(a) + (3 - 5)color(blue)(b) =>`

`3color(red)(a) + (-2)color(blue)(b) =>`

`3color(red)(a) - 2color(blue)(b)`
