Question

4x'y, -3xy, -5xy, 5xy​

Answer 1

Answer:

System of Linear Equations entered :

[1] 4x - 3y = -5

[2] x - y = -3

Graphic Representation of the Equations :

-3y + 4x = -5 y + x = -3 . see the attachment now

Solve by Substitution :

// Solve equation [2] for the variable x

[2] x = y - 3

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

[1] 4•(y -3) - 3y = -5

[1] y = 7

// Solve equation [1] for the variable y

[1] y = 7

// By now we know this much :

x = y-3

y = 7

// Use the y value to solve for x

x = (7)-3 = 4

Solution :

{x,y} = {4,7}
