x+7=3x+3 4=2x 4/2=2 x=2
3x = x + 4 x = 2 3x2=6 2+4=6
It is: 3x^2 +15x +12
Multiply out the factors and then you can check: (x + 2)(x + 3) = x² + 3x + 2x + 6 = x² + 5x + 6 ≠ x² + 3x + 4 Therefore False.
3x^2+3x-60=3(x^2+x+20)=3(x+5)(x-4)
x+7=3x+3 4=2x 4/2=2 x=2
x = 7 and 2/3
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
3x = x + 4 x = 2 3x2=6 2+4=6
It is: 3x^2 +15x +12
x^2 + 3x + 3 = 7 x^2 + 3x - 4 = 0 (x - 1)(x + 4) = 0 x = 1 or x = -4
(4x^3 + 2x^2 + 3x + 4)/(x + 4) = 4x^2 - 14x + 59 - 232/(x + 4)
x=2
Multiply out the factors and then you can check: (x + 2)(x + 3) = x² + 3x + 2x + 6 = x² + 5x + 6 ≠ x² + 3x + 4 Therefore False.
2(3x + 4) + 5x - 2
3x + 2 = -10 3x = -12 x = -4
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
