Question

Solution of equation 2m+7=9 is m=______ *
​

Answer 1

Given,

An equation 2m + 7 = 9

To find,

The value of m

Solution,

2m + 7 = 9

• +7 which is on the Left-Hand Side of the equation would shift to the Right-Hand Side of the equation and its sign would change from + 7 to -7.

Therefore we will get,

⇒   2m = 9 - 7

⇒   2m = 2

• +2 which is on the Left-Hand Side of the equation in the numerator would shift to the Right-Hand Side of the equation in the denominator.

⇒    m = 2/2

⇒    m = 1

Hence, the value of m for equation 2m + 7 = 9 is m =1

Answer 2

Solution of equation 2m + 7 = 9 is m = 1

Given :

The equation 2m + 7 = 9

To find :

The solution of the equation

Solution :

Step 1 of 2 :

Write down the given equation

Here the given equation is

2m + 7 = 9

Step 2 of 2 :

Find the solution of the equation

$\displaystyle \sf{ 2m + 7 = 9}$

$\displaystyle \sf{ \implies 2m = 9 - 7}$

$\displaystyle \sf{ \implies 2m = 2}$

$\displaystyle \sf{ \implies m = \frac{2}{2} }$

$\displaystyle \sf{ \implies m = 1 }$

Hence the required solution is m = 1
