Answer 2

Answer:

$x=-\frac{2}{3}$

Step-by-step explanation:

Given : The equation $3+2x=1-x$

To find : Solve the equation and check your result?

Solution :

Step 1 - Write the expression,

$3+2x=1-x$

Step 2 - Take like term together,

$2x+x=1-3$

Step 3 - Solve,

$3x=-2$

$x=-\frac{2}{3}$

To check the result substitute x on both side,

LHS - $3+2x$

$=3+2(-\frac{2}{3})$

$=3-\frac{4}{3}$

$=\frac{9-4}{3}$

$LHS=\frac{5}{3}$

RHS - $1-x$

$=1-(-\frac{2}{3})$

$=1+\frac{2}{3}$

$=\frac{3+2}{3}$

$RHS=\frac{5}{3}$

So, LHS=RHS the solution is true.
