Answer 2

AnSwer:-

• Add 3$x$ + 11 and 7$x$ - 5

The sum = 3 $x$ + 11 + 7$x$ -5 .

Now,we know that the terms 3$x$ and 7$x$ are like terms and so also are 11 and -5 .

Further 3$x$ + 7$x$ = 10$x$ = 10$x$ and 11 + (-5) = 6 .

We can,therefore,simplify the sum as :

The sum = 3$x$ + 11 + 7$x$ -5

= 3$x$ + 7$x$ + 11 -5 (Rearranging terms)

= 10$x$ + 6 .

Hence,3$x$ +11 + 7$x$ -5 = 10$x$ + 6.
