Question

solve the following equations and verify. 4x-9=7​

Answer 1

Answer:

Step-by-step explanation:

4x - 9 = 7

4x = 7 + 9 = 16

x = 16 / 4 = 4

∴ x = 4

Answer 2

Answer:

The value of $4x-9=7$ will be 4 and it satisfies the equation.

Step-by-step explanation:

As per the data given in the question,

We have to find the value of the equation and also we have to verify it,

The given equation,

$4x-9=7$

Here we will use the transposition method,

Transposing $9$ on the right side,

=> $4x = 7 + 9$

Add the numbers,

=> $4x = 16$

Divide both sides by $4$,

=> $x = 4$

Verification:-

Now, plug the value of x in the equation,

=> $4x-9=7$

=> 4 ( 4 ) - 9 = 7

=> 16 - 9 = 7

=> 7 = 7

LHS = RHS
