Answer:
The solution is (2,1).
Explanation:
We have the ordered pair;
5x - 3y = 7 ... (i)
-2x + 7y = 3 ... (ii)
Solving the simultaneous equations by elimination; we multiply (i) by 2 and (ii) by 5 to get:
10x - 6y = 14 ... (i)
-10x + 35y = 15 ... (ii)
Adding (i) and (ii) gives;
29y = 29
y = 29/29 = 1
Substituting y = 1 in equation (i) gives;
5x - 3(1) = 7
5x = 7 + 3
5x = 10 , x = 2
So the solution (x,y) is (2,1).
