To solve the equation -2x + 7 = 15, we need to isolate x on one side of the equation.
First, subtract 7 from both sides of the equation to get rid of the constant term:
-2x + 7 - 7 = 15 - 7
This simplifies to:
-2x = 8
Next, divide both sides of the equation by -2 to solve for x:
(-2x) / (-2) = 8 / (-2)
This simplifies to:
x = -4
Therefore, the solution to the equation -2x + 7 = 15 is x = -4.
-2x + 7 = 15
