Ответ:
The solution of the two give equations is (-1,4)
Step-by-step explanation:
i) First equation is y = -x + 3
ii) Second equation is y = x + 5
iii) If we add the two equations we get 2y = 8 ∴ y = 4
iv) Substituting the value of y obtained in iii) in equation i) we get
4 = -x + 3 ∴ -x = 4 - 3 ∴ -x = 1 ∴ x = -1
v) substituting x = -1 and y = 4 in the second equation we see that the equation is satisfied.
