Answer: x=-3
Step-by-step explanation:
First you add 3x+5x cause they are both variables.They equal 8x.
Then you subtract 7x from both sides to get x+17=10
then you subtract 17 from both sides.
you will get x= -3
Hope that helps!

From the given problem the same size is n = 70. Df = n – 1 =
70 – 1 = 69.
The population mean is u = 30, sample standard deviation is
s = 10 and the sample size is n = 70. Then,
t = x – u / s sqrt of n
1.995 = x – 30 / (10 sqrt of 70)
1.995 = x – 30 / 1.1952
X – 30 = 1.995 (1.1952)
X – 30 = 2.3844
X = 30 + 2.3844
X = 32.3844
The sample mean is 32.3844
