You simplify the expression to -3(x+4), then distribute -3 to x+4. -3•x=-3x and -3•4 is -12 so your final answer is -3x-12
Answer:
X=54
Step-by-step explanation:
180-126=54
the line has to be 180 so it has to be able to add to 126 and equal 180.
You can form an equation and solve it to find your answer:
(7 - s)/3 = 2
× 3
7 - s = 6
+ s
7 = 6 + s
- 6
s = 1
So your answer is 1, I hope this helps!
