See a solution process below:

First, rewrite the expression by grouping like terms:

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

Now, combine like terms:

$(7 - 4) a + (3 - 5) b \Rightarrow$ $(7 - 4)color(red)(a) + (3 - 5)color(blue)(b) =>$

$3 a + (- 2) b \Rightarrow$ $3color(red)(a) + (-2)color(blue)(b) =>$

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