4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
Y+7=9 equals 2+7=9.
If you mean: y = 3(-3/2)2+9(-3/2)-8 Then: y = -59/4 or as -14.75
17
6 + y = 8 y = 8 - 6 y = 2
y = 2 (4X2=8) +9 = 17
9
x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9
4x + y = 9 so that y = 9 - 4x 7x - 8y = 6 7x - 8*(9-4x) = 6 7x - 72 + 32x = 6 39x = 78 x = 2 Then y = 9 - 4x = 9-4*2 = 9-8 = 1
x + y = 10 y = x + 8 so, x + (x + 8) = 10 2x + 8 = 10 2x + 8 - 8 = 10 - 8 2x = 2 x = 1 and y = 9 because y = x + 8 y = 1 + 8 y = 9

Y+7=9 equals 2+7=9.
y1 = 2*(3/2)2 + 6*(3/2) + 9 = 18/4 + 18/2 + 9 = 221/2.y2 = 3*(-3/2)2 + 9*(-3/2) - 8 = 27/4 - 27/2 - 8 = 11/4.Another Answer:-If: y = 2(3/2)2-6(3/2)+9 then y = 4.5If: y = 3(-3/2)2+9(-3/2)-8 then y = -14.75
If you mean: y = 3(-3/2)2+9(-3/2)-8 Then: y = -59/4 or as -14.75
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72
If: 2y-10 = 8 Then: y = 9
