Question

2. Hallar x + y2, luego de resolver el sistema:
(4x + 2y = 5
(3x - 4y = 1​

Answer 1

4x + 2y = 5    //2

3x - 4y = 1​

--------------------------

8x + 4y = 10

3x - 4y = 1

--------------------------

11x = 11

x = 1

3(1) - 4y = 1

3 -4y = 1

-4y = 1-3

-4y = -2

y = 2/4

y = 1/2

Reemplazando:

x + y² = 1 + (1/2)² = 1 + 1/4 = (4+1)/4 = 5/4
