2a+x+2+4=408
Combine a and a to get 2a.
2a+x+6=408
Add 2 and 4 to get 6.
2a+6=408-x
Subtract x from both sides.
2a=408-x-6
Subtract 6 from both sides.
2a=402-x
Subtract 6 from 408 to get 402.
\frac{2a}{2}=\frac{402-x}{2}
Divide both sides by 2.
a=\frac{402-x}{2}
Dividing by 2 undoes the multiplication by 2.
a=-\frac{x}{2}+201
Divide 402-x by 2.
2a+x+2+4=408
Combine a and a to get 2a.
2a+x+6=408
Add 2 and 4 to get 6.
x+6=408-2a
Subtract 2a from both sides.
x=408-2a-6
Subtract 6 from both sides.
x=402-2a
Subtract 6 from 408 to get 402.
