Answer:
7x+3
Step-by-step explanation:
To simpfly, it would help by simply ignoring the variable (x) and just looking at the number before it, solving it like a regular math problem, from left to right.
9(x) - 2(x) = 7(x)
(-4)-(-7) = 3 --> since there's a minus sign in the middle subtracting the two numbers and one on the -7, the -7 becomes a positive 7. A negative times a negative is always positive so, it would technically be -4+7=3.
Put both of these two numbers together and you get your answer,
7x+3.
If you're having trouble with the part I explained the image might help. Read it from left to right. A negative # + a negative # = positive #, as seen by the first row.
Can you please say that in english?
Yes, that is correct. I checked it on my calculator. Good job!

This question is based on logic.
As given, there are three friends, Jose, Michael, and Andrea. They are playing a game where each decides to be either a liar or a truth teller. A liar must always lie and a truth teller must always tell the truth.
As Michael stated, "Jose said that he is a liar." this means Michael is a truth teller because as per the game rule, he is telling the truth. So this gives Jose as a liar.
Andrea said, " If one of us is a liar, then we are all liars." This makes Andrea a liar as Michael's statement already proved that he is the truth teller.
Hence, Michael is a truth teller and Jose ans Andrea are liars.
