\lambda -2=6-3\lambda
Multiply both sides of the equation by 3.
\lambda -2+3\lambda =6
Add 3\lambda to both sides.
4\lambda -2=6
Combine \lambda and 3\lambda to get 4\lambda .
4\lambda =6+2
Add 2 to both sides.
4\lambda =8
Add 6 and 2 to get 8.
\lambda =\frac{8}{4}
Divide both sides by 4.
\lambda =2
Divide 8 by 4 to get 2.
