The square of \sqrt{2} is 2.
30-112\times \frac{5\sqrt{2}}{4}x=y+xz\times 654
Multiply 2 and 2 to get 4.
30-28\times 5\sqrt{2}x=y+xz\times 654
Cancel out 4, the greatest common factor in 112 and 4.
30-140\sqrt{2}x=y+xz\times 654
Multiply 28 and 5 to get 140.
30-140\sqrt{2}x-xz\times 654=y
Subtract xz\times 654 from both sides.
30-140\sqrt{2}x-654xz=y
Multiply -1 and 654 to get -654.
-140\sqrt{2}x-654xz=y-30
Subtract 30 from both sides.
\left(-140\sqrt{2}-654z\right)x=y-30
Combine all terms containing x.
\left(-654z-140\sqrt{2}\right)x=y-30
The equation is in standard form.
\frac{\left(-654z-140\sqrt{2}\right)x}{-654z-140\sqrt{2}}=\frac{y-30}{-654z-140\sqrt{2}}
Divide both sides by -140\sqrt{2}-654z.
x=\frac{y-30}{-654z-140\sqrt{2}}
Dividing by -140\sqrt{2}-654z undoes the multiplication by -140\sqrt{2}-654z.
x=-\frac{y-30}{2\left(327z+70\sqrt{2}\right)}
Divide y-30 by -140\sqrt{2}-654z.
