x= Negative 4
X=7
x=1
It is a quadratic equation with one unknown variable, x which has no real roots.
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
2x = -7 - 8y
x = 15
X=27
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
x = 4 and y = 7
"minus negative x" means "plus x" (2x - 5)(x + 2) or (2x + 5)(x - 2) depending on what you really meant...
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
2x+7x-10=4x+3-2x 9x-10=2x+3 7x=13 x=13/7ans
An equation where x equals 3.
-2x=2y-4 2x-y=-5 Answer=(-1,3)
x = 4 and y = 7 which will satisfy both equations
[ y = 2x plus or minus any number ] is parallel to it. [ y = -0.5x plus or minus any number ] is perpendicular to it.
2x+3-7=0 2x=4 x=2
