How to solve 3x+2y=2;2x+3y=8
Asked by parthekbote | 08 Apr, 2019, 06:00: PM
Expert Answer
3x + 2y = 2 ....(i)
2x + 3y = 8 ....(ii)
Adding (i) and (ii)
5x + 5y = 10
x + y = 2 ....(iii)
Subtracting (ii) from (i)
x - y = -6 ....(iv)
adding (iii) and (iv) we get
2x = -4
x = -2
Put it in (i) we get
-6 + 2y = 2
2y = 8
y = 4
x = -2 and y = 4
