Determine the best method to solve the system of equations. x = 2y – 1
3x + y = 11
Please do your best to get it correct. Thanks

Polygons efgh and e′f′g′h′ are shown on the coordinate grid: what set of transformations is performed on efgh to form e′f′g′h′? a. a translation 1 unit to the left followed by a 90-degree counterclockwise rotation about the origin b. a translation 1 unit to the right followed by a 90-degree counterclockwise rotation about the origin c. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the right d. a 90-degree clockwise rotation about the origin followed by a translation 2 units to the left

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
