Answer:
x=250y+86
Step-by-step explanation:
add 250 to both sides
x−250y+250y=86+250y
x=250y+86
Answer:
Step-by-step explanation:
Let sharma age be S and Ankit age be A
S = 3a
(s-10) = 5(a-10)
substitute 1 in 2
3a-10 = 5a -50
40 = 2a
a = 20
s = 3 * 20 = 60

The product of the rational expressions
= ![\dfrac{7x^2}{x^2+3x-28}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%5E2%7D%7Bx%5E2%2B3x-28%7D)
</h2>
Step-by-step explanation:
We have,
![\dfrac{7x}{x-4}.\dfrac{x}{x+7}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%7D%7Bx-4%7D.%5Cdfrac%7Bx%7D%7Bx%2B7%7D)
To find, the product of the rational expressions
= ?
∴ ![\dfrac{7x}{x-4}.\dfrac{x}{x+7}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%7D%7Bx-4%7D.%5Cdfrac%7Bx%7D%7Bx%2B7%7D)
= ![\dfrac{7x.x}{(x-4)(x+7)}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x.x%7D%7B%28x-4%29%28x%2B7%29%7D)
= ![\dfrac{7x^2}{(x(x+7)-4(x+7)}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%5E2%7D%7B%28x%28x%2B7%29-4%28x%2B7%29%7D)
= ![\dfrac{7x^2}{x^2+7x-4x-28}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%5E2%7D%7Bx%5E2%2B7x-4x-28%7D)
= ![\dfrac{7x^2}{x^2+3x-28}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%5E2%7D%7Bx%5E2%2B3x-28%7D)
Thus, the product of the rational expressions
= ![\dfrac{7x^2}{x^2+3x-28}](https://tex.z-dn.net/?f=%5Cdfrac%7B7x%5E2%7D%7Bx%5E2%2B3x-28%7D)
