multiply both sides by 3/7
3/7(7/3)x=105(3/7)
and x =45

When you have a fraction on a variable, multiply both sides by the reciprocal of that fraction. All you have to do is turn it upside down and multiply. The two equal one on the "x" side, and then figure out the other.
3/7*(7/3x)=105* 3/7
x=35

Just multiply!
3x(X)105= 7
315x=7
x = 7/315
See...get a calculator and x = 7 divided by 315

7/3x=105
crossing:
7x = (105 * 3)
x = 315 : 7

Assuming question should read as:-
(7/3) x = 105
7 x = 315
x = 45

7/3x =105
7=105 * 3x
7=315x
x=7/315
x=0.02222
