Answer:
(4, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 13 → (1)
5x + 6y = 38 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the y- term
- 2x - 6y = - 26 → (3)
Add (2) and (3) term by term to eliminate y
3x + 0 = 12
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
4 + 3y = 13 ( subtract 4 from both sides )
3y = 9 ( divide both sides by 3 )
y = 3
solution is (4, 3 )
