Question

If m=(2x+1) and n=(6) and m+n=(9). Find x​

Answer 1

Answer:

$\Large \boxed{x=1}$

Step-by-step explanation:

Substitute m=(2x+1) and n=(6) in m+n=(9).

We are finding the value of the x variable.

$2x+1+6=9$

Add the numbers on the left side of the equation.

$2x+7=9$

Subtract 7 from both sides.

$2x+7-7=9-7$

$2x=2$

Divide both sides by 2.

$\displaystyle \frac{2x}{2}=\frac{2}{2}$

$x=1$

The value of the x variable is 1.
