Question

solve the equation 7x-9 =16​

Answer 1

Answer:

let ,x= 1

put value of 1 in equation

$7x - 9 = 16$

$7 \times 1 - 9 = 16$

$7 - 9 = 16$

$- 2 = 16$

$= 18$

Answer 2

Answer:

=> The value of x is $\frac{25}{7}.$

Step-by-step explanation:

Given that:-

$7x-9 =16$

To find:- The value of the expression,

For solving this expression, we must apply the transposition method:

As we have,

=> $7x-9 =16$

Add both sides by $9$, we get

=> $7x-9 +9=16+9$

Simplifying it further, we get

=> $7x = 16 + 9$

Add the numbers,

=> $7x = 25$

Divide both sides by $7$,

=> $x = \frac{25}{7}$

Hence, the required solution is $\frac{25}{7}.$
