E=\left(2x+1\right)\times 3
Subtract 1 from 4 to get 3.
E=6x+3
Use the distributive property to multiply 2x+1 by 3.
E=\left(2x+1\right)\times 3
Subtract 1 from 4 to get 3.
E=6x+3
Use the distributive property to multiply 2x+1 by 3.
6x+3=E
Swap sides so that all variable terms are on the left hand side.
6x=E-3
Subtract 3 from both sides.
\frac{6x}{6}=\frac{E-3}{6}
Divide both sides by 6.
x=\frac{E-3}{6}
Dividing by 6 undoes the multiplication by 6.
x=\frac{E}{6}-\frac{1}{2}
Divide E-3 by 6.
