Question

if 5x/3 - 4= 2x/5 then value of x/60+18/19 is​

Answer 1

Answer:

5x/3 - 4= 2x/5

5x-12/3=2x/5

25x-60=6x

25x-6x=60

19x=60

x=60/19

value of x/60+18/19

60/19*60+18/19

60/1140+18/19

60+1080/1140

1140/1140

Answer 2

Answer:

The value of x/60+18/19 is 1.

Step-by-step explanation:

Here given,

$\frac{5x}{3} - 4= \frac{2x}{5}$

So,

$\frac{5x - 4 \times 3}{ 3} = \frac{2x}{5} \\ \frac{5x - 12}{3} = \frac{2x}{5}$

By cross multiplication,

$5(5x - 12) = 3 \times 2x \\ 25x - 60 = 6x \\ 25x - 6x = 60 \\ 19x = 60 \\ x = \frac{60}{19}$

Now we want find value of

$\frac{x}{60 } + \frac{18}{19} \\ = \frac{ \frac{60}{19} }{60} + \frac{18}{19} \\ = \frac{60}{19 \times 60} + \frac{18}{19} \\ = \frac{1}{19} + \frac{18}{19} \\ = \frac{1 + 18}{19} \\ = \frac{19}{19} \\ = 1$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
