Answer 2

Solving for x in the Equation 3x + 7 = -2

To solve for the value of x in the equation 3x + 7 = -2, we can use algebraic manipulation to isolate x.

First, we subtract 7 from both sides of the equation: 3x + 7 - 7 = -2 - 7 This simplifies to: 3x = -9

Next, we divide both sides by 3 to solve for x: 3x / 3 = -9 / 3 This simplifies to: x = -3

Therefore, the value of x in the equation 3x + 7 = -2 is x = -3.

The solution for x in the equation 3x + 7 = -2 is x = -3
