Question

How do you solve $ 6 - x - 3 = 4x - 12 $

Answer 1

Hint: In the question, we are provided with a linear equation with only one variable. We have to find the value for the variable “x”. solve the expression by taking the variables to the left-hand side and take the constants to the other side and solve to find the value of “x”.

Complete step by step solution:
In this question, we are given an expression with “x” as its variable. And we have to find the value for the variable “x”.
For solving these questions, take the variables at one side and the constants at the other side.
 $
  6 - x - 3 = 4x - 12 \\
  4x + x = 6 - 3 + 12 \;
  $
Do the simple calculations by doing addition on the left-hand side and the other simple calculations on the other side.
 $ 5x = 15 $
Dividing by $ 5 $ on both sides,
 $\Rightarrow x = \dfrac{{15}}{5} = 3 $
So, the value of “x” is $ 3 $ . This is our required answer.
So, the correct answer is “x=3”.

Note: Linear equations are quite easier to solve. The difficulty level is when we have to find two variables to solve. Just keep in mind to have constants on the right-hand side and the variables to the left-hand side. solve the simple calculations carefully.
