Answer:
26
Step-by-step explanation:
We are told that x=4, which means you will substitute 4 in for every x.
So for 3x, you would do 3(4) because the x = 4. Just substitute 4 in for the x.
3(4) - 6 + 7(4) - 2(4)
Now, you could put that in a calculator or solve it on paper. :) If you're doing it on paper, remember PEMDAS.
12 - 6 + 28 - 8
= 26
