A-95.

For the following equations, solve for x. Check your solution, if possible. Record your work. Homework Help ✎

  1. 3x − 7 = 3x + 1

  2. −2x − 5 = −4x + 2

  3. 2 + 3x = x + 2 + 2x

  4. −(x − 2) = x + 2

Add 7 to both sides.

3x − 7 = 3x + 1
+7 +7

Subtract 3x from both sides.

3x = 3x + 8
−3x −3x

0 = 8

The statement is not true;
therefore, the answer is: No Solution.
