Here you go! I hope this help! Remember that negative times negatives are positive, positive times a positive is a positive, and a negative times a positive is a negative!
Correct Work
-2(7+x) - 4(9-x)
-14- 2x -36 + 4x
-2x+4x-14-36
2x-50
Mistakes made
- The likes terms weren't combined
- -6x was incorrect. -2x+4x = 2, when adding negative and positive numbers you subtract, the sign takes the number with the larger value which is +4 so the answer should be positive +
