Answer: x= -1, y = 2 Answer in detail: First, multiply the first equation with 3 (x + 2y =3) 3 = 3x + 6y = 9 Taking the difference of the equations 3x + 6y = 9 – 3x + 5y =7 _______________ 0 +1 y = 2 y = 2 Equating the value of y in eq. 1 x + 2y = 3 x + 2*2 = 3 x + 4 = 3 x = 3-4 = -1 Reply
Answer: x= -1, y = 2
Answer in detail:
First, multiply the first equation with 3
(x + 2y =3) 3 = 3x + 6y = 9
Taking the difference of the equations
3x + 6y = 9
–
3x + 5y =7
_______________
0 +1 y = 2
y = 2
Equating the value of y in eq. 1
x + 2y = 3
x + 2*2 = 3
x + 4 = 3
x = 3-4 = -1
