Answer:
Step-by-step explanation:
To solve this equation, you put -1 in the both x's
-3 X -1 - 4 X -1
Then you solve -3 times -1 to get 3 (a negative times a negative makes a positive)
After that you solve for 4 - (-1) to get -4 (a negative times a positive makes a negative)
Then you subtract 3 from -4 to get the answer
3- (-4) = 7
