6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
The above expression simplifies to 2x-y+9z
x = -8, y = 10
-4x + 6y - 5z = 60At the x-intercept, 'y' and 'z' are zero:-4x = 60 ===> x = -15At the y-intercept, 'x' and 'z' are zero:6y = 60 ===> y = 10At the z-intercept, 'x' and 'y' are zero:-5z = 60 ===> z = -12
8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1
4x+6y=62 -6x+6y=-18 what is the ordered pair
The given algebraic expression can be simplified to: 14y+4x
6x + 3y + 6y - 2x = (6x - 2x) + (3y + 6y) = 4x + 9y
y=4x+2
4x + 3y = 6y 4x = 3y 4/3 x = y The slope is 4/3 and the y intercept is 0.
8y-7x
Collect like terms: 3x - x + 4x - 4y + 6y + 2 = 6x + 2y + 2
y-5x
Let's see if I can answer this. 4X + 6Y + 3Y + 4W + 6X - 7W = (4 + 6)X + (6 + 3)Y + (4 - 7)W = 10X + 9Y - 3W
It does nothing! 4x + 6y = 24 7x + 6y = 9 Subtracting the first equation from the second gives: 3x = - 15 so that x = -5 Substituting the value of x in the first equation gives -20 + 6y = 24 so that 6y = 44 and so y = 22/3 or 71/3
(2, 1)
Subtracting gives: 10x = 80 so x = 8 and y = 5
