If m=(2x+1) and n=(6) and m+n=(9). Find x<br>​
gregori [183]

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.
