The answer would be 22.

You would use the order of operations to solve this problem,

First you do the parenthesis, there are none so you skip this

Then the exponents, none so skip it

Then you do multiplication and division from left to right

5•7 is 35, 3•8 is 24

So the problem is now
35-24+11

After multiplication comes addition and subtraction from left to right

35-24 is 11
11+11 = 22

So the answer to (5x7)-(3x8)+11 is 22

Hey there!

If,
c = 7 and
d = 8

Then, let's solve the equation, shall we?


5(7) -3(8)
+ 11


5(7) = 35


35 - 3(8)
+ 11


3(8) = 24


35 - 24
+ 11


35 - 24
= 11


11 + 11 =
= 22

Answer:
22

Good luck on your assignment and enjoy your day!
