The table can be used to determine the solution of equations, 2x β 2y = 6 and 4x + 4y = 28.
a table with 6 columns and 2 rows. the first column, original system has 2 x minus 2 y equals 6 and 4 x plus 4 y equals 28. the second column, equivalent system, has 4 x minus 4 y equals 12 and 4 x plus 4 y equals 28. the third column, sum of equations in equivalent system, has 8 x equals 40. the fourth column, solution to system, is blank. the fifth column, new system using sum, has 4 x plus 4 y equals 28 and 8 x equals 40. the sixth column, solution to new system is blank.
which solution can be used to fill in both blanks in the table?
(2, 5)
(5, 2)
(5, β8)
(β8, 5)
