A system of equations can be solved by elimination in the table below.
1
5x + 3y = 14
4x - 2y = -2
2
2(5x + 3y) = 2(14)
4x - 2y = -2
5x + 3y = 14
3(4x - 2y) = 3(-2)
3
10x + 6y = 28
4x - 2y = -2
5x + 3y = 14
12x - y = -6
10x + 6y = 28
12x - 5y = -6
Does the system of equations on line 4 have the same solution set as the system of equations on line
1? Why or why not?

Which expression is rational? 6. , square root two, square root 14, square root 49
