I am needing help with the following questions
solve the linear system of equations
1) x – 3y = -6
5x + 3y = 42
2) 2x – 6y = 7
5x + 2y = 10
3) x + 16y = 9
1/4 x + 4y = 8
4) 3x – 2y = 7
9x – 6y = 14
Determine whether the system of linear equations has one and only one solution, infinitely many solutions, or no solution. Find all solutions whenever they exist.
5) x + 3y = 9
3x – y = 7
6) 2x – 5y = 10
4x – 10y = 20
Solve the linear system of equations
7) 7/4 x – 5/2 y = 2
1/4 x + 7/2 y = 8
8) 9x – 7y = 63
45 x – 35y = 18
9) A system composed of two linear equations must have at least one solution if the straight lines represented by these equations are nonparallel. True or False
Solve the linear system of equations
10) 6x – 7y = 20
3x + 5y = -7
Solve the system of linear equations using the Gauss- Jordan elimination method.
11) x – 2y = 8
3x + 4y = 8
12) 3x + 2y = 14
x – 4y = -14
13) 7x + 5y = 32
3x + y =-20
14) 3x + 3y + z = 22
x + z = 6
4y – 3z = 8
15) 2 x + 5 y – 2 z = 14
5 x – 6 y + 2 z = 0
4 x – y + 3 z = -7
