Question

3 + 2x = 1 - x solve it​

Answer 1

Answer:

Answer

The value of the variable which makes the equation a true statement is called the root of the equation.

Now, to find the value of x by considering the given equation,

3+2x=1−x

⇒x+2x=1−3

⇒(1+2)x=−2

⇒3x=−2

⇒x=

3

−2

Now, to check the result .

we have to substitute

3

−2

in the place of x in given equation.

So, we get LHS of given equation as

LHS=3+2×(

3

−2

)

=3−2×

(3×3)−4

=

Now, RHS will be

RHS=1−(

3

−2

)

=1+

1×3+2

=

∴LHS=RHS

Hence , the result is verified.
