What is the mistake in this solving of an equation 3x minus 12 equals 10x minus 15 minus 6x minus 10 3x minus 12 equals 4x minus 25 3x plus 13 equals 4x 13 equals x?
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
What is the answer to 4x plus 6x equals 30?
4x+6x=30 is the same as: 10x=30 so we divide by 10 and get: x=3 (I do not see how this relates to calculus, but O.K.)
What is the answer to 10x - 4x plus 5 x 2 - 6 x equals -2x?
x=5. 10x-4x (6x) +10-6x (=10) If 10 is 2x, x=5.
2x plus 5 equals 7-4x?
2x + 5 = 7 - 4x ie 2x + 4x = 7 - 5 ie 6x = 2 x = one third.
What does x equal in 6x equals 12?
If: 6x = 12 Then: x = 2
6x plus 4 equals x plus 12 plus 4x-6?
6x+4 = x+12+4x-6 6x-x-4x = 12-6-4 x = 2
2x plus 6x plus 4x 12?
2x + 6x + 4x = 12x
4X-12 plus 6X equals 8?
Add 12 to each side: 4x + 6x = 20 ie 10x = 20 so x = 2
6x-12 plus 4x plus 5?
6x - 12 + 4x + 5 = 06x + 4x = 12 - 510x = 7x = 7/10
What is 6x plus 34 equals 4x plus 284?
6x + 34 = 4x +284 6x - 4x = 284 - 34 2x = 250 x = 125
What does 3 plus 6x equals 4x plus 9?
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
Solve -4x plus 3 equals 23 plus 6x?
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
4x plus 6y equals 62 and -6x plus 6y equals -18?
4x+6y=62 -6x+6y=-18 what is the ordered pair
6x plus 10 plus 4x equals 50?
6x + 10 + 4x = 5010x + 10 = 5010x = 40x = 4
2x plus 9 equals 6x - 3?
2x+9=6x-3 Therefore 4x=12 -->x=3
6x-52 equals 4x plus 40?
6x-52 = 4x+40 6x-4x = 40+52 2x = 92 Answer: x = 46
4x-8 equals 12 plus 6x?
4x - 8 = 12 + 6x 4x - 6x = 12 + 8 -2x = 20 -x = 20/2 x = -10 Check: 4(-10) - 8 = 12 + 6(-10) -40 - 8 = 12 + -60 -48 = -48
