If 3(x+1) = 2(x+4)
expand the equations
3x+3 = 2x+8
subract (2x+3) from both sides
x = 5

Let x= the number, therefore;
3x+1= 2x+4
(subtract 2x from both sides of the equation)
1x+1=4
(now subtract 1 from both sides)
Therefore, 1x=3 or simply, x=3
Now test it yourself. Go back to the original equation and substitute the number 3 for X and see if it fits. Good luck!

enable the 1st variety be x 2d variety = x - 4 0.33 variety = 4x basically about all those whilst upload up equals to sixty two Mathematically, x + (x - 4) + 4x = sixty two 6x - 4 = sixty two 6x = sixty two + 4 6x = 66 x = 66/6 x = 11 First variety = 11 2d variety = 11 - 4 = 7 0.33 variety = 11 x 4 = 40 4 The numbers are 7, 11 and 40 4

ur question is not clear. tere are two possibility :
one
3x+1=2x+4
3x=2x+3
x=3
two
3(x+1) = 2(x+4)
3x + 3 = 2x + 8
3x - 2x = 8 - 3
x=5
Depends on how it actually is.
