The solution to the given expression is (-2, 4)
System of equation
This are equations that consists of several equations and unknowns.
Given the system of equations below
2x + 5y = 16
-5x - 2y = 2
Using the elimination method
10x +25y = 80
-10x - 4y = 4
Add
25y - 4y = 84
21y = 84
y =4
Recall
-5x - 2y = 2
-5x - 8 = 2
-5x = 10
x = -2
Hence the solution to the given expression is (-2, 4)
