In the solution of bivariate linear equation 3x-4y = 4, if x and y are equal, what is the solution of this equation? In the solution of bivariate linear equation 2x + 5Y = 6, if x and y are opposite to each other, what is the solution of this equation?

In the solution of bivariate linear equation 3x-4y = 4, if x and y are equal, what is the solution of this equation? In the solution of bivariate linear equation 2x + 5Y = 6, if x and y are opposite to each other, what is the solution of this equation?

1.3x-4y=4
x=y
x=-4 y=-4
2.2x+5y=6 x=-y
x=-2 y=2

Given that the quadratic equation 3x + 4Y + 6 = 0, when x and y are opposite numbers, x =, y =

6,-6
X=-Y
-3Y+4Y+6=0
Y=-6
X=6

Given the quadratic equation x + y = 7,3x + 4Y = 19, then X-Y = () x + y = ()

x+y=7----①3x+4y=19-----②
4 ① - ② get x = 9, substitute ①, get y = - 2
So X-Y = (11), x + y = (7)

Solve the following quadratic equation x / 3-y / 4 = 1 3x-4y = 2

X / 3-y / 4 = 1. Multiply this equation by 12 to get 4x-3y = 12, and then combine with the second equation to get x = 6 and y = 4
