x=4
x = 2
-4x-6x = -20 -10x = -20 Divide both sides by -10 rembering that a minus divided into a minus the result is positive: x = 2
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
4x -17 equals 3 4x equals 20 x equals 5
4x + 20
It is possible.
6x - 4y
The slope is 4
4x = 20 x = 5 (divide both sides by 4)
4x2 - 20 = 0∴x2 - 5 = 0∴x2 = 5∴x = √5
The slope of f(x) = 3-4x is -4.
4x - 7 = 5 + 7x x = -4
