The given system of equations is expressed as
x + y = 25
8x + 6y = 190
From the first equation,
x = 25 - y
Substituting x = 25 - y into the seconmd equation, it becomes
8(25 - y) + 6y = 190
200 - 8y + 6y = 190
Collecting like terms, it becomes
- 8y + 6y = 190 - 200
- 2y = - 10
Dividing both sides of the equation by - 2, it becomes
- 2y/- 2 = - 10/ - 2
y = 5
x = 25 - y = 25 - 5
x = 20
(20, 5)
