X=9
You add 3 to both sides which leaves you with 2x=18 and then divide by two and that gives you x=9
Answer:
D
Step-by-step explanation:
7x + 28 < 84
- 28 -28
7x < 56
÷7 ÷7
x < 8
If it was a negative 7 the arrow would change direction
Assuming you mean

first term is n=1, so 1²+3=1+3=4
2nd is n=2 so 2²+3=4+3=7
3rd is n=3 so 3²+3=9+3=12
the first 3 terms are 4,7,12
Answer:
X= 22
Step-by-step explanation:
x-5=17
To solve,
Since five is being subtracted from x, to get x by itself, add five to both sides
x-5=17
+5 +5
X= 22
The answer is 22 :)
