5(4x-3y = 11)
4(5x+4y = 6)
Multiply the top equation by 5 and the bottom by 4:
20x-15y = 55
20x+16y = 24
Subtract:
-31y = 31
y = -1
Substitute the value of y into the original equations to find the value of x:
So: x = 2 and y -1

the answer
(0,7)
To solve for two unknowns (x and y) it is necessary to have two independent equations.
x = 6 and y = -2
To solve an equation with three unknowns, x, y and z, you require 3 independent equations.
-2 plus 5 equals +3
