The equation 3x + 1 = 3x + 2 has no solution.

3x + 1 = 3x + 2;

3x - 3x = 2 - 1;

0 = 1

3x + 1 = 3x + 2;

3x - 3x = 2 - 1;

0 = 1

The sequence 0,...-1/8, -1/4, -1/2 does not have a common difference, it has a common ratio.

Solve for x.
3(x + 5) - 2(x + 2) = 20
1
9
13 **Weegy:** Simplifying
-6x + -2 = 40
Reorder the terms:
-2 + -6x = 40
Solving
-2 + -6x = 40
Solving for variable 'x'.
Move all terms containing x to the left, [ all other terms to the right.
Add '2' to each side of the equation.
-2 + 2 + -6x = 40 + 2
Combine like terms: -2 + 2 = 0
0 + -6x = 40 + 2
-6x = 40 + 2
Combine like terms: 40 + 2 = 42
-6x = 42
Divide each side by '-6'.
x = -7
Simplifying
x = -7

3(x + 5) - 2(x + 2) = 20

3x + 15 - 2x - 4 = 20

3x - 2x = 20 -15 + 4

x = 9

3x + 15 - 2x - 4 = 20

3x - 2x = 20 -15 + 4

x = 9
