so = -4y < -20 making y < 5
4y+6+9=4y+15
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
This simplifies to 3x-6+4y.
6+(-2x-8)-(-3+12x)-(4y)= 6-2x-8+3-12x-4y=1-14x-4y 1-14x=4y (1-14x)/4=y
so = -4y < -20 making y < 5
4y+6+9=4y+15
4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
6-2x-8+3+12x+4y 10x+4y+1 Note that - -3 = +3 and that - -4y = +4y
5y + 6
This simplifies to 3x-6+4y.
6+(-2x-8)-(-3+12x)-(4y)= 6-2x-8+3-12x-4y=1-14x-4y 1-14x=4y (1-14x)/4=y
If: -4y+7 = 35-6 then y = -5.5
First rearrange these simultaneous equations in the form of: 7x-4y = 26 5x-4y = 14 Subtract the bottom equation from the top equation remembering that a - - is equal to a plus. So, -4y - - 4y = 0 2x = 12 and therefore it follows that x = 6 Substitute the value of x into the original equations to find the value of y: Therefore: x = 6 and y = 4
(4y + 1)(y + 6)
2 - 8y + 6 = 4y - 702 + 6 + 70 = 4y + 8y78 = 12yy = 78/12y = 6.5
-6 + 3x - y - 4x + 4y + 5 (combine like terms) = (-6 + 5) + (3x - 4x) + (-y + 4y) = -1 - x + 3yHope this helps :)
