First multiply by 9x. 7 = 378x. Divide each side by 378 to isolate x. 1/54 = x. Check your answer: 7/(1/6) does indeed equal 42.
I'm assuming you meant (7/9)x = 42.
If that's correct, then we can quickly and easily solve for x by multiplying both sides of this equation by 9/7:
(9/7)(7/9)x = (9/7)(42) = 54. x = 54
1.25x40=50
