Correct Answer

Explanation

To find the value of c, we can substitute -2 for x in the equation and solve for c.Given the equation: 2x + 1 - 3c = 2c + 3x - 7Substituting x = -2:2(-2) + 1 - 3c = 2c + 3(-2) - 7Simplifying:-4 + 1 - 3c = 2c - 6 - 7-3c - 3 = 2c - 13Rearranging terms:-3c - 2c = -13 + 3-5c = -10Dividing both sides by -5:c = -10 / -5c = 2Therefore, the value of c is 2.
