3x - y = 0 . . . (1)
5x + 2y = 22 . . . (2)
From (1), y = 3x . . . (3)
Putting (3) into (2) gives:
5x + 2(3x) = 22
5x + 6x = 22
11x = 22
x = 2
From (3), y = 3(11) = 33
x = 11, y = 33.
The Solution.
The given equation is
Substituting 11 for x, we can get the value of y.
Hence, the value of y is 18.
3 + 3 + 1 = 7
3 + 3 are the double ones
+1
=7
