5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
10x - 5x + 5x = 10x
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
5x+8 = 10x+35x-10x = 3-8-5x = -5x = 1 and by substituting the value of x into the equations y = 13
-10x + 5x = -5x
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
x = 10x, so derivative = 10
x=-3
6-3x = 5x-10x+2 4 = 8x-10x 4 = -2x x = -2
45-5x = 5x+55 -5x-5x = 55-45 -10x = 10 x = -1
10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z
You find x. Oh! There it is!! ^ See?
15x = -75, x = -5
5x + 10x doesn't need factorization as you can just add them up (5x+10x=15x). However, if you really want to, 5x+10x=5x(1+2)=5x(3)=15x
6-3x = 5x-10x+10 6-3x = -5x+10 -3x+5x = 10-6 2x = 4 x = 2
10x - 78 = 1, 10x = 79, x = 7.9
x=12
9 degrees
15x
5x + 32 = 11x - 105x - 11x = -10 - 32-6x = -42x = 7
12 - 3x = 24 - 10x so 7x = 12 making x = 12/7 or one and five-sevenths.
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
5x+5x-10 10x-10 is the only answer you can get from this
The equation 10x - 15x + 5 = -45 + 40 can be simplified to -5x + 5 = -5. By moving the numbers to one side, it becomes -5x = -10, to 5x = 10, then x = 2.
