Question

solve this equation through substitution​

Answer 1

The given pair of equations are:

x2x2 + y = 0.8 ⇒ x + 2y = 1.6……

(a) 7/(x + y2y2) = 10 ⇒7 = 10(x +y2y2) ⇒7 = 10x + 5y

Let’s, multiply LHS and RHS of equation (a) by 10 for easy calculation

So, we finally get 10x + 20y = 16. .(i)

And, 10x + 5y = 7. (ii)

Now, subtracting two equations we get, ⇒ (i) – (ii) 15y = 9 ⇒ y = 3535

Next, putting the value of y in the equation (i) we get,

x = [16 − 20(3/5)]/10 ⇒

(16–12)10(16–12)10 = 410410

∴ x = 2525 Thus, the value of x and y obtained are 2525 and 3535 respectively
