Answer:
Step-by-step Simplifying
6 + -3x = 4 + -1x + -3 + -2x
Reorder the terms:
6 + -3x = 4 + -3 + -1x + -2x
Combine like terms: 4 + -3 = 1
6 + -3x = 1 + -1x + -2x
Combine like terms: -1x + -2x = -3x
6 + -3x = 1 + -3x
Add '3x' to each side of the equation.
6 + -3x + 3x = 1 + -3x + 3x
Combine like terms: -3x + 3x = 0
6 + 0 = 1 + -3x + 3x
6 = 1 + -3x + 3x
Combine like terms: -3x + 3x = 0
6 = 1 + 0
6 = 1
Solving
6 = 1
Couldn't find a variable to solve for.
This equation is invalid, the left and right sides are not equal, therefore there is no solution.

Answer:
a) the value of 135 because it is not greater than 136.5
Step-by-step explanation:
Given that
n = sample size =85
Mean = 146
std dev =34
Std error of sample = 34/sqrt 85
= 3.6878
99% z critical value = 2.58
Margin of error = ±9.515
Confidence interval lower bound = 146-9.515 = 136.485
Upper bound = 146+9.515 =155.515
Hence we find that 135 is less than lower bound, hence 135 does not lie within 99% confidence interval
a) the value of 135 because it is not greater than 136.5
