Answer:
(1, 2 )
Step-by-step explanation:
Giving the 2 equations
2x + y = 4 → (1)
x - y = - 1 → (2)
Adding the 2 equations term by term, eliminates the term in y
3x = 3 ( divide both sides by 3 )
x = 1
Substitute x = 1 into either of the 2 equations for corresponding value of y
Substituting x = 1 into (1)
(2 × 1) + y = 4
2 + y = 4 ( subtract 2 from both sides )
y = 2
Solution is (1, 2 )
