Answer:
x = 3, y = -4
Step-by-step explanation:
Given the simultaneous equation:
4x + y = 8 ....1
2x - y = 10 ....2
Using the Elimination method
Add both equations
4x + 2x = 8 + 10
6x = 18
Divide both sides by 6
6x/6 = 18/6
x = 18/6
x = 3
Substitute x = 3 into equation 1;
From 1;
4x+y = 8
4(3) + y = 8
12 + y = 8
y = 8 - 12
y = -4
Hence the solution to the system of equation is (3, -4)
