Answer:
(2, 0 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 4 → (1)
3x - 7y = 6 → (2)
Multiplying (1) by 3 and (2) by - 2 and adding the result will eliminate x
6x + 9y = 12 → (3)
- 6x + 14y = - 12 → (4)
Add (3) and (4) term by term to eliminate x
0 + 23y = 0
23y = 0
y = 0
Substitute y = 0 into either of the 2 equations and solve for x
Substituting into (1)
2x + 3(0) = 4
2x = 4 ( divide both sides by 2 )
x = 2
solution is (2, 0 )
Answer: The first step would be to multiply the first equation by 3 and the second by 2 so you can eliminate x.
