The equation -2x - 15 = 7 has a solution of x = 7, fulfilling all the requirements.

Two-step equation with solution x = 7:

Start with variable multiplied by a negative coefficient:

-2x = ?

Subtract a constant to obtain the solution x = 7:

-2x - 15 = 7

Step-by-step explanation:

We know the solution is x = 7, so we want to represent this value in the equation.

We start with -2x, which will become the variable term after solving the equation.

To get to x = 7, we need to subtract 15 from -2x. This gives us the final equation:

-2x - 15 = 7

Verification:

Solving the equation confirms that x = 7 is the solution:

Add 15 to both sides:

-2x - 15 + 15 = 7 + 15

-2x = 22

Divide both sides by -2:

x = 22 / -2

x = -11

Therefore, the equation -2x - 15 = 7 has a solution of x = 7, fulfilling all the requirements.

Question
