3 ln(x) = ln(3x)
ln(x3) = ln(3x)
x3 = 3x
x2 = 3
x = sqrt(3)
x = 1.732 (rounded)
Get in function form. - 3X - Y = 4 - 1(- Y = 3X + 4) Y = - 3X - 4 ----------------------------solve for X and Y by the 0 out method - 3X - 4 = 0 - 3X = 4 X = - 4/3 --------------- Y = - 3(0) - 4 Y = - 4 -------------- Draw a line linking those points.
6x2 = -7x -2 6x2 + 7x + 2 = 0 6x2 + 3x + 4x + 2 = 0 3x(2x + 1) + 2(2x + 1) = 0 (2x + 1)(3x + 2) = 0 2x + 1 = 0 or 3x + 2 = 0 So, x = -1/2 or -2/3
so, if 2 minus Ln times 3 minus x equals 0, then 2 minus Ln times 3 equals x, therefore 2 minus Ln equals x divided by three, so Ln + X/3 = 2 therefore, (Ln + [X/3]) = 1
If: 3x+y = 4 and x+y = 0 Then: x = 2 and y = -2
3x2+x-4 = 0 (3x+4)(x-1) = 0 Solutions: x = 1 and x = -4/3 By using the quadratic equation formula.
3x2-9x = 0 x(3x-9) = 0 x = 0 or x = 3

5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
x2 plus 3x plus 3 is equals to 0 can be solved by getting the roots.
(3x+4)(3x-4)=0 x=±4/3
2x(3x+6) = 0 x = 0 or x = -2
-3x2 + 22x = 0 You start by dividing both sides by x: ∴ -3x + 22 = 0 Then rearrange to solve for x: ∴3x = 22 ∴ x = 7 + 1/3
2x+3x-2=0=5x=0+2=5x=2=5x_5=2_5=x=0.4
3x2 + x - 2 = 0(3x - 2) (x + 1) = 0x = + 2/3x = -1
what does the equation equal? if it equals zero: 0= 3x(4-11) 0=3x(-7) 0=3x 0=x if the equation doesn't equal anything, it means it's just an expression meaning you can't solve for x, you can only reduce (and this equation is already reduced). if the equation equals y, you need another equation and use either substitution or elimination to solve for x.
x = 25 / 3squared + 5
x = 4 and y = 0
