Pls answer it i wil give more points

What is the solution of the systems of equations? y=2/3x+3 x=-2

Nick has box brads. he uses 4 brads for the first project. nick let’s b represent the original number of brads and finds that for the second project, the number of brads he uses is 8 more than half the difference of b and 4. write an expression to represent the number of brads he uses for the second project.

What are the solutions of the system? solve by graphing. y = -x^2 -6x - 7 y = 2
