x_{0}\times 2+x+x=276
Cancel out 0.2 and 0.2.
x_{0}\times 2+2x=276
Combine x and x to get 2x.
2x=276-x_{0}\times 2
Subtract x_{0}\times 2 from both sides.
2x=276-2x_{0}
Multiply -1 and 2 to get -2.
\frac{2x}{2}=\frac{276-2x_{0}}{2}
Divide both sides by 2.
x=\frac{276-2x_{0}}{2}
Dividing by 2 undoes the multiplication by 2.
x=138-x_{0}
Divide 276-2x_{0} by 2.
x_{0}\times 2+x+x=276
Cancel out 0.2 and 0.2.
x_{0}\times 2+2x=276
Combine x and x to get 2x.
x_{0}\times 2=276-2x
Subtract 2x from both sides.
2x_{0}=276-2x
The equation is in standard form.
\frac{2x_{0}}{2}=\frac{276-2x}{2}
Divide both sides by 2.
x_{0}=\frac{276-2x}{2}
Dividing by 2 undoes the multiplication by 2.
x_{0}=138-x
Divide 276-2x by 2.
