Answer:
x = 3, y = 1
Step-by-step explanation:
Given the 2 equations
2x + y = 7 → (1)
3x - 4y = 5 → (2)
Multiplying (1) by 4 and adding to (2) will eliminate the y- term
8x + 4y = 28 → (3)
Add (2) and (3) term by term to eliminate y
11x = 33 ( divide both sides by 11 )
x = 3
Substitute x = 3 into either of the 2 equations and solve for y
Substituting into (1)
2(3) + y = 7
6 + y = 7 ( subtract 6 from both sides )
y = 1
solution is x = 3 and y = 1
