Y = 9x - 2
3x - 2y = 7
so sub in 9x - 2 for y in the 2nd equation and solve for x

3x - 2(9x - 2) = 7
3x - 18x + 4 = 7
3x - 18x = 7 - 4
-15x = 3
x = -3/15
x = -1/5 or - 0.2 <===

6(x²-4x+4-4)+1=0, 6(x-2)²-24+1=0, 6(x-2)²=23, x-2=±√(23/6), x=2±√(23/6)=2±1.95789, so x=3.95789 or 0.04211 approx. These are the zeroes.
