6y 10+4y subtract 4y from each side 2y 10 divide both sides by 2 y = 5
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
but crack
the system of equations 3x-6y=20 and 2x-4y =3 is?Well its inconsistent.
It is: 3x+10y+5 simplified
6y 10+4y subtract 4y from each side 2y 10 divide both sides by 2 y = 5
By definition: 4y-2 = 6y+8 4y-6y = 8+2 -2y = 10 y = -5 and by substituting this value into the equation x = -22
-6y + 14 + 4y = 32-2y = 32 - 14-2y = 18y = - 9
but crack
x = 4y - 2x = 6y + 84y - 2 = 6y + 8Subtract 4y from each side:-2 = 2y + 8Subtract 8 from each side:-10 = 2yDivide each side by 2:-5 = yx = 4y - 2x = -22
(4, -2)
y = ½ (6y = 3)
Algebra4y-4 plus y plus 24 equals 6y plus 20-4YCombine like terms5y+20=2y+20Isolate Y3y=0y=0
3y - 7 + y + 27 = 6y + 20 - 4y Collect terms: 4y + 20 = 2y + 20 Subtract 20 4y = 2y The only way that can happen is if y = 0
26 = -6y + 6 + 2y = -4y + 6 Subtracting 6 from both sides: 20 = -4y Dividing both sides by (-4): -5 = y
Two straight lines that intersect.
10y = 2y - 6y + 7 10y =-4y + 7 10y +4y = 7 14y = 7 y = 1/2 = .5
