Which solution shows that each pair of equations is equivalent.

substituting 7 for a; 10-7 = 3; resulting in 3=3 and therefore equivalent

substituting 7 for a; 10-7 = 3; resulting in 17=3 and therefore not equivalent

1

Which solution shows that each pair of equations is equivalent.

substitute 4 for n; 9=4+5; resulting in 9=-1 and therefore not equivalent

substitute 4 for n; 9=4+5; resulting in 9=9 and therefore equivalent

1

Which solution shows that each pair of equations is equivalent.

substitute -5 for x; 7 = 12 - 5 results in 7=7 and therefore are equivalent

substitute -5 for x; 7 = 12 - 5 results in 17=17 and therefore are equivalent

1

Which solution shows that each pair of equations is equivalent.

substituting 11 for y; 4 - 11 = -7; results in -7=-7 and therefore are equivalent

substituting 11 for y; 4 - 11 = -7; results in 18=18 and therefore are equivalent
