Solution for 2x+1=5x-5 equation

Simplifying

2x + 1 = 5x + -5

Reorder the terms:

1 + 2x = 5x + -5

Reorder the terms:

1 + 2x = -5 + 5x

Solving

1 + 2x = -5 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

1 + 2x + -5x = -5 + 5x + -5x

Combine like terms: 2x + -5x = -3x

1 + -3x = -5 + 5x + -5x

Combine like terms: 5x + -5x = 0

1 + -3x = -5 + 0

1 + -3x = -5

Add '-1' to each side of the equation.

1 + -1 + -3x = -5 + -1

Combine like terms: 1 + -1 = 0

0 + -3x = -5 + -1

-3x = -5 + -1

Combine like terms: -5 + -1 = -6

-3x = -6

Divide each side by '-3'.

x = 2

Simplifying

x = 2

6. Often, judging the symmetry and skewness of such distributions is not easy to do by eye, especially when they are asymmetrical or skewed in different ways. Here, the mean of set A is about 7, so the data is skewed to the left more than for set B, which has a mean of about 5.4--closer to the middle of the range.

Both data sets have the same range: 2–10. Set A's mode of 8 is higher than set B's mode of 6.

Hence, the only true statement appears to be

... B. Set B has the lesser mean.
