-3x plus 6 plus 15x equals 11x plus 8?
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
What is x in the equation 3x plus 8 equals 20?
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
3x plus 5x equals -8 then x plus 1 equals?
If 3x + 5x = -8, what is x + 1? 3x + 5x = -8 8x = -8 x = -1 x + 1 = -1 + 1 = 0
3x plus 11 equals x plus 3?
3x + 11 = x + 3 2x = -8 x = -4
What is the solution of 3x plus 8 equals 23?
3x + 8 = 23 Subtract 8 from both sides: 3x = 15 Divide both sides by 3: x = 5
Y equals 4X2 plus 3x plus 8?
y=4x2+3x+8
3x plus 8 equals 2x plus 28?
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
What is the x 3x plus 5 equals 20?
3x + 5 = -20. First, subtract 5 from both sides of the equation: 3x + 5 - 5 = -20 - 5; and simplify: 3x = -25. Then divide both sides by 3: 3x / 3 = -25 / 3; and simplify: x = -8 1/3 (or -8.33)
What does 4x plus 5 equals 3x plus 8 equal?
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
What is 3x plus 8 equals 12?
3x+8 = 12 3x = 4 x = 4/3
What is this equation in standard form 3x equals 6y plus 8?
3x-6y=-8
8 plus 7x equals 20 plus 3x what is x?
8+7x = 20+3x 7x-3x = 20-8 4x = 12 x = 3
What is the answer to 4 plus 6x equals 5 plus 3x plus 7?
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
-3x - 8 plus 6x equals 7?
3x - 8 = 7 so x = 5
Find the solution 3x-3y equals 12 and 3x plus y equals 8?
70000000y=35t
-3x plus 6 plus 15x equals 11x plus 8?
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
What is x in the equation 3x plus 8 equals 20?
3x + 8 = 20 3x = 20 - 8 3x = 12 3x = 12/3 x = 4
