Question

Can you please Simplify 4a+7b+5a-b

Answer 1

For this, you would need to combine your like terms

In this case your like terms are 4a and 5a : 7b and -b

So, all you do is add

4a + 5a= 9a

7b + (-b) or if it is easier to understand you can write it as 7b - b

When adding these two together, b contains an invisible one in front of it so if you feel the need to, you can also write the equation as:

7b + (-1b) or 7b - 1b

7b - 1b= 6b

Your answer is 9a + 6b

Side note: anytime you have a single variable ( just a or b or x) any single variable with no number in front of it, that means there is an invisible one in front of it ( 1a or 1b or 1x)

Hope this helps :)

Answer 2

9a+6b is the answer. You can find this by grouping the like terms.
