3x - 5 = 9 3x = 9 + 5 3x = 14 x = 14/3 or 4 2/3
5x + 4 - 3x + 5 + 2x - 9 = 4x
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
We need to get both equations into slope-intercept form. If they are parallel, they will have the same slope. If they are perpendicular, they will have slopes that when multiplied equal -1. (unless one line is horizontal and the other vertical) 3x+2y=5 2y=5-3x y=(-3/2)x+(5/2) 3x+2y=9 2y=9-3x y=(-3/2)x+(9/2) The two lines are parallel, since both slopes are equal to (-3/2).
7x - 9 = 3x + 5 7x - 3x - 9 = 5 7x - 3x = 5 + 9 4x = 14 x = 14/4
3x+5=14 3x=9 x=3
x= 1.67(rnd) 5= -4+3x+4 5- -4= 9 9=3x+4 9-4=5 5=3x x= 1.67(rnd)
3x + 4 = 4x - 5 Add 5 to both sides: 3x + 9 = 4x Subtract 3x from both sides: 9 = x
the answer is -3x = 0
3x+5=14 3x+5-5=14-5, -5 on both side 3x=9 (3x)/3=9/3, dividing by 3 on both side, so x=3
10-6+5 = 9
3x-1+10 = 53x + 9 = 53x = 5 - 93x = -4x = -4/3
It is a linear equation in one variable, x.
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
4x + 2 = 3x + 9 x + 2 = 9 x = 7
The equivalent expression of 3x-9 plus 3x plus 5 is negative 4.
