Answer:
what do you need help with?
Step-by-step explanation:
The function of 5 (or y when x is 5) can not be determined with this little information.
41/10
4.1 = 4 1/10 = 41/10
number - n
Twice a number - 2n
Seven times the number - 7n
2n = 7n +35
7n-2n = -35
5n = -35
n = - 7
Check:
2(-7) = 7(-7) +35
-14 = -49 + 35
-14 = -14 True
The number is (- 7).
