3x = (96-75) 3x = 21So X = 7
8-3x = 128 -3x = 128-8 -3x = 120 x = -40
3x+4=10 To solve: 3x+4=10 3x=6 x=2
3 ln(x) = ln(3x)ln(x3) = ln(3x)x3 = 3xx2 = 3x = sqrt(3)x = 1.732 (rounded)
x + 2x = 33 3x = 33 3x/3 = 33/3 x = 11
X + X/2 = 45 so 3X/2 =45 3X=90 X=30
In this equation, 3x + 9 = 45. To solve for x, you need to subtract 9 from both sides of the equation, which gives you 3x = 36. To find the value of x, you need to divide both sides of the equation by 3, which gives you x = 12. Therefore, the value of x is 12.
3x=24 x=8
you multiply by its denominator to each side. Example: 3x/5=9 now multiply by 5 to each side 3x/5 times 5 is 3x and 9 times 5 is 45 so you get 3x=45 now divide by 3 to each side and you get x=15
Let the number be x: 3x-9 = 45 3x = 45+9 3x = 54 x = 18
3x-11 for x=9
3x = (96-75) 3x = 21So X = 7
3x=96-75 3x=21 x=7
If: 3x = 45 Then: x = 15
3x - 4 = -2 The answer is x=2/3
x=7
g (x) = -3x+5 -3x= 5 x= -5/3
