Answer


\boxed{ \boxed{ \bold{ \red{ - 4a + 5b}}}}

Step by step explanation


\sf3(a + b) - 2(2a - b) + 4a - 7a

Distribute 3 through the parentheses


\sf3a + 3b - 2(2a - b) + 4a - 7a

Distribute 2 through the parentheses


\sf3a + 3b - 4a + 2b + 4a - 7a

Collect like terms


\sf3a +4a - 4a - 7a + 3b + 2b

Since , two opposites add up to zero, remove them from the expression


\sf3a - 7a + 3b + 2b


\sf - 4a + 5b

Hope I helped!

Best regards!!
