Question

If 3 + 2x = 1 – x then x = ?​

Answer 1

Step-by-step explanation:

+2x

x+2x

3x

x

=1−x

=1−3

=−2

=

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

2

=3−

3

4

=

3

Now, RHS will be,

RHS

=1−(

3

−2

)

=1+

3

2

=

3

1×3+2

=
