3x-4y = 8
-4y = -3x+8
y = 3/4x-2 or y = 0.75x-2 which is the equivalent in slope intercept form

x= 24x2 = 8
When x equals -8 and y equals 3, the expression -xy becomes -(-8)(3). Multiplying -8 and 3 gives us -24. Therefore, -xy equals -24 in this scenario.
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
Sure thing, honey. If a equals 8, then you just substitute that bad boy in for a in the expression a-2. So, 8-2 equals 6. Ta-da! Your answer is 6. Hope that clears things up for ya, sugar.
4+9+7+6+8+8 equals 42.42 divided by 6 equals 7.
