Answer:
(x, y) = (4, 1)
Step-by-step explanation:
We assume you want to solve ...
- x +y = 5
- 5x -3y = 17
Multiply the first equation by 3 and add the second:
3(x +y) +(5x -3y) = 3(5) +(17)
8x = 32 . . . . . . simplify
x = 4 . . . . . . . . .divide by 8
4 +y = 5 . . . . . . substitute into the first equation
y = 1 . . . . . . . . .subtract 4
The solution is (x, y) = (4, 1).
