Answer 1

Respuesta:

// Solve equation [2] for the variable x

[2] x = y + 24

// Plug this in for variable x in equation [1]

[1] (y +24) + y = 10

[1] 2y = -14

// Solve equation [1] for the variable y

[1] 2y = - 14

[1] y = - 7

// By now we know this much :

x = y+24

y = -7

// Use the y value to solve for x

x = (-7)+24 = 17

Solution :

{x,y} = {17,-7}
