Solve each system of equations. State whether it is an inconsistent system or has infinitely many solutions. If a system has infinitely many solutions, write the solution set with x arbitrary. See Examples 3 and 4.9x - 5y = 1 -18x + 10y = 1

Solve each system by elimination. In systems with fractions, first clear denominators. See Example 2.x/2+ y/3 = 43x/2+3y/2 = 15

Solve each system by elimination. In systems with fractions, first clear denominators. See Example 2.(2x-1)/3 + (y+2)/4 = 4(x+3)/2 - (x-y)/2 = 3

In Exercises 19–30, solve each system by the addition method.3x = 4y + 13y = 1 - 4x

In Exercises 31–42, solve by the method of your choice. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets. x = 9-2yx + 2y = 13

In Exercises 31–42, solve by the method of your choice. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets. y = 3x - 521x - 35 = 7y

In Exercises 31–42, solve by the method of your choice. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets. 3x - 2y = − 54x + y = 8

Solve each system of equations. State whether it is an inconsistent system or has infinitely many solutions. If a system has infinitely many solutions, write the solution set with x arbitrary. See Examples 3 and 4.5x - 5y - 3 = 0 x - y - 12 = 0

In Exercises 31–42, solve by the method of your choice. Identify systems with no solution and systems with infinitely many solutions, using set notation to express their solution sets. x + 3y = 23x + 9y = 6
