The first thing you want to do is combine like terms. This means you should have all the x's on one side and the constants (numbers) on the other side. You can subtract 5x from both sides of the equation and then add 7 to both sides. This gives you -2x=26. Divide both sides be -2 to isolate the variable and your answer is x=-13. Hope this helped!
Answer:
First ?: 4
Second ?: -6
Step-by-step explanation:
40-40=0, which leaves 4n left.
34-40=-6
The final answer would be n= 3/2.
20% of 307.32 = 61.464 (Rounded to the nearest tenth, 61.46)
307.32 - 61.46 = $245.86
Answer:
It will be x^7
Step-by-step explanation:
If a term doesn't have an exponet then it's considered 1. Then you're going to add all numbers which is, 1+2+4 which equals 7. So then that makes x^7.
