Step-by-step explanation:
To solve the given linear equation, -3x = 27, for the variable x, divide both sides of the equation by -3 in order to isolate x on the left side, thus solving the equation for x as follows:
-3x = 27 (Given)
(-3x)/-3 = 27/-3
(-3/-3)x = 27/-3
(1)x = -9
x = -9
CHECK (ALWAYS PERFORM THIS STEP, AND DO SO BACK IN THE ORIGINAL, GIVEN EQUATION!):
-3x = 27
-3(-9) = 27
27 = 27
Therefore, x = -9 is indeed the solution to the given equation.
REMEMBER: For solving equations, WHATEVER YOU DO TO ONE SIDE OF THE EQUATION, YOU MUST DO TO THE OTHER SIDE.
