Since the 7 is in front of the parentheses you must multiply it by everything inside the parentheses. 7 times X is 7X and 7 times -2 is -14. Then you need to make the X be by itself on one side, to do that you have to add 14 to -14 to make it disappear, and also add 14 to the other side, to 28. Then you divide both sides by 7 to make X be by itself.
7(x-2)=28
7X-14=28
7x=42
X=6
Answer:
-45 + 12 is equal to -33
and <u>Choice A </u> is also equal to -33.
Step-by-step explanation:
-28/9-(-5 5/9)
-28/9-(50/9)
-28/9-50/9
22/9
= 2 4/9= 2.444444

If n is 2, you substitute 2 for n and multiply 5(2)+8= 10 +8 = 18
