\frac{1}{3}x+2x-7=\sqrt{26}x+1
Calculate the square root of 4 and get 2.
\frac{7}{3}x-7=\sqrt{26}x+1
Combine \frac{1}{3}x and 2x to get \frac{7}{3}x.
\frac{7}{3}x-7-\sqrt{26}x=1
Subtract \sqrt{26}x from both sides.
\frac{7}{3}x-\sqrt{26}x=1+7
Add 7 to both sides.
\frac{7}{3}x-\sqrt{26}x=8
Add 1 and 7 to get 8.
\left(\frac{7}{3}-\sqrt{26}\right)x=8
Combine all terms containing x.
\frac{\left(\frac{7}{3}-\sqrt{26}\right)x}{\frac{7}{3}-\sqrt{26}}=\frac{8}{\frac{7}{3}-\sqrt{26}}
Divide both sides by \frac{7}{3}-\sqrt{26}.
x=\frac{8}{\frac{7}{3}-\sqrt{26}}
Dividing by \frac{7}{3}-\sqrt{26} undoes the multiplication by \frac{7}{3}-\sqrt{26}.
x=\frac{-72\sqrt{26}-168}{185}
Divide 8 by \frac{7}{3}-\sqrt{26}.
