2-2/3x = 4/5x
The common denominator of 3x and 5x is 15x so multiply all terms by 15x in order to eliminate the fractions:
30x-10 = 12
30x = 22
Divide both sides by 30 in order to find the value of x:
x = 22/30 = 11/15 in its lowest terms
Substituting the value of x into the original equation: 12/11 = 12/11
Therefore the solution is correct

15x minus 8=minus 180 3x+8=24
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
6x-3x =6 3x=6 so 6 divided by 3 = 2
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.

3x-y=9 y=3x-9
15x minus 8=minus 180 3x+8=24
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
6x-3x =6 3x=6 so 6 divided by 3 = 2
3x-6 = 21 3x = 21+6 x = (21+6)/3 x = 9 You shouldn't ask us to solve your math homework.
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
x = 25 / 3squared + 5
7x+6 = -3x-24 7x+3x = -24-6 10x = -30 x = -3
6 - 3x = 4 - 2x 6 = x + 4 x = 2 Check it. 6 - 6 = 4 - 4 It checks.
3x+4 = 5x-6 3x-5x = -6-4 -2x = -10 x = 5
3x2 + x - 2 = 0(3x - 2) (x + 1) = 0x = + 2/3x = -1
