The value of x and y from the simultaneous equation; 3x + 2y = 19, 4x - y = 29 is 7 and -1 respectively.
How to solve simultaneous equation?
3x + 2y = 19 (1)
4x - y = 29 (2)
Multiply (2) by 2
8x - 2y = 58 (3)
Add (1) and (3)
3x + 2y = 19 (1)
8x - 2y = 58 (3)
11x = 77
x = 77/11
x = 7
- substitute x = 7 into (2)
4x - y = 29 (2)
4(7) - y = 29
28 - y = 29
subtract 28 from both sides
-y = 29 - 28
-y = 1
y = -1
Therefore, the solution to the equation is (x, y) = (7, -1)
