To solve the linear equation, we can isolate the variable x by subtracting 3 from both sides of the equation.
Starting with: -x + 3 = 15
Subtracting 3 from both sides:
-x + 3 - 3 = 15 - 3
-x = 12
To solve for x, multiply both sides of the equation by -1 to eliminate the negative sign in front of x.
Multiplying both sides by -1:
(-1)(-x) = (-1)(12)
x = -12
Therefore, x = -12.
