Answer:
a) 2-5 = -3
b) 3(4) + 2(4) = 20
c) (3(5)+2)(5-4) = 17
Step-by-step explanation:
Substitute the variables for their values and then solve from there. Hopefully this helps, I don't know if I answered your question fully.

Answer:
2x + 3t - 4
Step-by-step explanation:
Hi,
To simplify the expression, we must combine like terms. To start, let's combine all of the x-values.
4x + 3t - 2x - 4
When we combine 4x and -2x we get 2x.
2x + 3t - 4
We can't combine anything else. They don't have the same variables and 4 doesn't even have a variable, so 2x + 3t -4 is the simplified expression.
I hope this helps :)
