plz sum solve this plz​

Answer 1

Answer:

Number taken is 19.

Step-by-step explanation:

Let the number be x.

first multiply the number by 28.

$x \times 28$

then add 14 to product

$28x + 14$

divide the sum by 13

$\frac{28x + 14}{13}$

subtract 4 from the quotient

$\frac{28x + 14}{13} - 4$

this equation results to the double of the number taken

$\frac{28x + 14}{13} - 4 = 2x$

this is the final equation.

first multiply both sides by 13

$28x + 14 - 4 \times 13 = 2x \times 13$

which is equal to

$28x + 14 - 52 = 26x$

then subtract 52 from 14

$28x - 32 = 26x$

transfer -32 to rhs and 26x to lhs

$28x - 26x = 38$

$2x = 38$

$x = \frac{38}{2}$

$x = 19$
