Angle A is 30 more than twice angle B can be written as

A = 2B + 30

Because we know that angle A and angle B form a linear pair, we know that

A + B = 180

Plug the first equation into the second equation and solve for A. Once you solve for A, plug the know A value into into second equation and solve for B.
