Question

(4a - b) + (3a - 5b)

Answer 1

4a-b+3a-5b= 7a-6b

Answer 2

I went through an exact same question yesterday. Though I'll answer it.
Open the brackets.

\(\Large \color{MidnightBlue}{\Rightarrow 4a - b + 3a - 5b }\)

Operate on the like terms.
\(\Large \color{MidnightBlue}{\Rightarrow (4a + 3a) + (-b -5b) }\)
\(\Large \color{MidnightBlue}{\Rightarrow 7a - 6b }\)

Answer 3

Thanks.
