Answer:
(2, 5 )
Explanation:
5x - y = 5 → (1)
- x + 3y = 13 → (2)
multiplying (1) by 3 and adding to (2) will eliminate y
15x - 3y = 15 → (3)
add (2) and (3) term by term to eliminate y
14x + 0 = 28
14x = 28 ( divide both sides by 14 )
x = 2
substitute x = 2 into either of the 2 equations and solve for y
substituting into (2)
- 2 + 3y = 13 ( add 2 to both sides )
3y = 15 ( divide both sides by 3 )
y = 5
solution is (2, 5 )
