What is 3x y equals 4 and x y equals 0?
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
6x squared minus 58x plus 80 equals 0?
6x2 + 58x + 80 = 02(40 + 29x + 3x2) = 02((8 + x)(5 + 3x)) = 0, ignore 28 + x = 0 => x = -85 + 3x = 0 => 3x = 5 => x= 1.666666....x = {-8, 1.66....}
What is the answer to this equation 3x-1 equals 28?
3x - 1 = 28 3x = 29 x = 29/3 x= (approximately) 9.67
What mistake was made in this equation 3x plus 7 equals -4x plus 28 -x plus 7 equals 28 -x equals 21 x equals -21?
3x + 7 = -4x + 28 implies 7x + 7 = 28
3x - 1 equals 27?
3x - 1 = 27 So 3x = 28 and x = 28/3 = 91/3
3x plus 8 equals 2x plus 28?
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20

x=-5
What is 3x plus 6 plus 7 equals 28?
x = 5
What is x if x-3x equals 18?
If x-3x=18 then x equals -9
What is 3x plus 7y if x equals 6 y equals 4?
3x + 7y = 3*x + 7*y = 3*6 + 7*4 = 18 + 28 = 46
What is x in x -3x plus 7 equals 28?
x - 3x + 7 = 28 Collect the x together: x - 3x = (1-3)x = -2x → -2x + 7 = 28 Collect the numbers together - subtract 7 from both sides →-2x = -21 Divide both sides by -2 to get what one x is: x = -10.5
What does x equals in 3x 12 equals 18?
3x+12 = 18 3x = 18-12 3x = 6 x = 2
