-2x+y=8−2x+y=8minus, 2, x, plus, y, equals, 8.

3. solve by graphing: y = 2x + 6 x + y = -3

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
