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
