Question

Write the following statement by using appropriate grouping symbols:
The sum of $a-b$ and $3a-2b+5$ is subtracted from $4a+2b-7.$

Answer 1

The sum of $a-b$ and $3a-2b$ is written as $\left\{\right(a-b)+(3a-2b\left)\right\}$

Now, this sum is to be subtracted from $4a+2b-7$

So,

It can be written as :

$(4a+2b-7)-\left\{\right(a-b)+(3a-2b\left)\right\}$
