185=-1080a-9\left(37-161a\right)
Multiply both sides of the equation by -5.
185=-1080a-333+1449a
Use the distributive property to multiply -9 by 37-161a.
185=369a-333
Combine -1080a and 1449a to get 369a.
369a-333=185
Swap sides so that all variable terms are on the left hand side.
369a=185+333
Add 333 to both sides.
369a=518
Add 185 and 333 to get 518.
a=\frac{518}{369}
Divide both sides by 369.
