The value of x that makes the given equation true is C. x=−2.
What are linear equation?
A linear equation only has one or two variables. No variables in a linear equation is raised to power greater than 1 or used as denominator of a fraction.
Now the given equation is,
x − 3x = 2(4+x)
To find the value of x we need to solve the given equation,
First we do is open the bracket,
x − 3x = 8 + 2x
Solving L.H.S, we get
-2x = 8 + 2x
Substraction 2x both the sides,
- 2x - 2x = 8 + 2x - 2x
Solving them,
-4x = 8
Dividing the whole equation by -4 we get,
x = -2
which is the required value of x.
The value of x that makes the given equation true is C. x=−2.
