–2x + 3y = 7,

-2x = 7 - 3y

x = (3/2)y - 7/2

Replace x in the equation 4x – 6y = 8, then 4(3/2y - 7/2) - 6y = 8

6y - 14 - 6y = 8, the simplified form is 0 = 22 which is not true.

Therefore, the solution for –2x + 3y = 7 4x – 6y = 8 is D. no solution.

-2x = 7 - 3y

x = (3/2)y - 7/2

Replace x in the equation 4x – 6y = 8, then 4(3/2y - 7/2) - 6y = 8

6y - 14 - 6y = 8, the simplified form is 0 = 22 which is not true.

Therefore, the solution for –2x + 3y = 7 4x – 6y = 8 is D. no solution.
