Do you mean: 9x+9 = 4x+24
If so x = 3
-2x=-4x*24 x=12
4x+8y=-24
how do you use the substitution method for this problem 2x-3y=-2 4x+y=24
4x = 24 x = 24 ÷ 4 x = 6
4x+2y=24 => 2y=24-4x => y=12-2x and the slope is -2
-2x = -4x + 24 -2x + 4x = 24 2x = 24 x = 24/2 x = 12
4x = 24 is not any property. It is an equation which is true for some value of x, not for others.
4x-24y = 24 -24y = -4x+24 y = 1/6x-1 So the y intercept is -1
Gosh... 4X plus 6 equals 30... This concludes to: 4X= 4 x X All you have to do is work back wards!!!! I'm only in year 6!! 30-6=24 Which mean 4 x X=24 X=6!!!!!!!!! =D
X is 6
3y - 4x = 24 The first step is to write it in the standard form (y=mx + c) 3y = 4x + 24 y = (4x + 24)/3 y = 4x/3 + 8 The y-intercept is 8 and the slope/gradient is 4/3
2x + 6 - 6x = 30= 6 - 4x = 30= -4x = 24= 4x = -24= x = -6
