Multiply both sides of the equation by 4 at the same time to get: x- 1+2=4? ∴ x=3
Multiplying both sides of the equation by 9 at the same time gives 3x+2=33? ∴x=3 1/3
Multiply both sides of the equation by 3 at the same time to get 2x+2=2? ∴x=0
Multiply both sides of the equation by 24 at the same time to get 3x-3-9=20? ∴x= 14
Multiply both sides of the equation by 30 at the same time to get:? 3x+27+25=60？ ∴x=8/3
Ps: Because I don't know where your denominator is? So I solved it according to the general law. Like what? The question is x+9/ 10 X plus nine tenths or (x+9) tenths? I calculated it according to (x+9)/ 10. The same is true of other problems.
But the method is the same.
