Question

ANSWER THE EQUATION :

If X+2y =26 ,5y=35 then evaluate the value of 
${x}^{2} + {2y}^{2}$
​

Answer 1

Answer:

Explanation:

You can subtract the second equation from the first equation to eliminate y:

7x + y = 25 – 6x + y = 23: 7x – 6x = x; y – y = 0; 25 – 23 = 2

x = 2

You could also solve one equation for y and substitute that value in for y in the other equation:

6x + y = 23 → y = 23 – 6x.

7x + y = 25 → 7x + (23 – 6x) = 25 → x + 23 = 25 → x = 2
