The solution to the simultaneous equations, 5x + y = -5 and 5x – 3y = 11, is: (-1/5, -4)
What is the Solution of Simultaneous Equations?
The solution is the pair of values of x and y that is true for both equations.
Given the simultaneous equations,
5x + y = -5
5x – 3y = 11
Subtract
4y = -16
y = -4
Substitute y = -4 into equation 1.
5x + (-4) = -5
5x - 4 = -5
5x = -5 + 4
5x = -1
x = -1/5
