Question

The value of x in 4x/5 -1=7 is​

Answer 1

Step-by-step explanation:

$\frac{4x}{5} - 1 = 7 \\ \\ \frac{4x - 5}{5} = 7 \\ 4x - 5 = 7 \times 5 \\ 4x - 5 = 35 \\ 4x = 35 + 5 \\ 4x = 40 \\ x = 10$

Answer 2

Answer:

=> The value of x is 10.

Step-by-step explanation:

Given that:-

$\frac{4x}{5}-1=7$

To find:- The value of the expression,

We must use the transposition method to determine the value of x:

As we have,

=> $\frac{4x}{5}-1=7$

First of all, we have to find the common denominator:

=> $\frac{4x}{5}-\frac{5(-1)}{5} =7$

Simplifying it further, we get

=> $\frac{4x+5(1)}{5}=7$

Multiplying the number,

=> $\frac{4x-5}{5}=7$

Now multiply both sides by $5$, for removing term in the denominator

=> $\frac{4x-5}{5}\times 5=7\times 5$

=> $4x -5 = 7\times 5$

=> $4x -5 = 35$

Add both sides by $5$,

=> $4x -5+5 = 35+5$

=> $4x = 40$

Divide both sides by $40$,

=> $x = 10$

Hence, the required solution is 10.
