Question

3a + 5b - 4a + 2b = * 7a 23ab a + b -a + 7b

Answer 1

Answer:

-a + 7b

Step-by-step explanation:

This problem is asking you to simplify the equation.

In order to do this, we will combine like terms (like terms are terms that share the same variable and/or exponent).

So we will combine 3a and -4a to get -1a or just -a, and now we'll combine 5b and 2b to get 7b.

So all together we have -a + 7b.

Hope this helps you :)

Answer 2

$\\ \sf\Rrightarrow 3a+5b-4a+2b$

$\\ \sf\Rrightarrow 3a-4a+5b+2b$

$\\ \sf\Rrightarrow (3-4)a+(5+2)b$

$\\ \sf\Rrightarrow -a+7b$

$\\ \sf\Rrightarrow 7b-a$
