Solve for x: 6 - 3x = 18
Understand the Problem
The question asks to solve a simple linear equation for the variable 'x'. This involves isolating 'x' by performing algebraic operations on both sides of the equation.
Answer
$x = -4$
Answer for screen readers
$x = -4$
Steps to Solve
-
Subtract 6 from both sides To isolate the term with $x$, subtract 6 from both sides of the equation: $6 - 3x - 6 = 18 - 6$ This simplifies to: $-3x = 12$
-
Divide both sides by -3 To solve for $x$, divide both sides of the equation by -3: $\frac{-3x}{-3} = \frac{12}{-3}$ This simplifies to: $x = -4$
$x = -4$
More Information
The solution to the equation $6 - 3x = 18$ is $x = -4$. This value of $x$ makes the equation true.
Tips
A common mistake is to add 6 to both sides instead of subtracting. Also, forgetting the negative sign when dividing can lead to an incorrect answer.
