Answer:
4x-43
Explanation:
Here we have to simplify the expression 7(x – 4) – 3(x + 5)
In order to do so we first open the two brackets using distributive laws.
7(x – 4) – 3(x + 5)= 7*x-7*4-3*x-3*5
= 7x-28-3x-15
Now we bring the terms containing the x together and the terms not containing x together
= 7x-3x-28-15
we simplify them
= 4x-43
Hence
7(x – 4) – 3(x + 5)=4x-43 is the simplified expression
