2x + 3y = 16.95 x
3y = 16.95 x - 2x
3y. = 14.95x.........first equation
and
2x + 3y = y + 7.4
2x +3y -y = 7.4
2x + 2y = 7.4
2(x+y) =7.4
x+ y = 7.4 / 2 = 3.7
y = 3.7 - x
putting the value of y in first equation:
3* (3.7-x) = 14.95 x
11.1 - 3x = 14.95 x
11.1 = 14.95x + 3x
17.95x = 11.1
x = 11.1 / 17.95
and
y = 3.7 - 11.1 / 17.95
hope it helps u.
