Answer:
(0, 4 )
Step-by-step explanation:
5x + 2y = 8 → (1)
- 4x + 10y = 40 → (2)
multiplying (1) by - 5 and adding to (2) will eliminate y
- 25x - 10y = - 40 → (3)
add (2) and (3) term by term to eliminate y
- 29x = 0 , then
x = 0
substitute x = 0 into (1) and solve for y
5(0) + 2y = 8
0 + 2y = 8
2y = 8 ( divide both sides by 2 )
y = 4
solution is (0, 4 )
