9x(7x+1/2)=3x+(1/2X)
9x7x=2x
2x+1/2=3x+1/2x
2x+1/2=2x+1/2
2x=2x
x=x

\[9x 1(7x+\frac{ 1 }{ 2 }) = 3x + 1(\frac{ 1 }{ 2 }x)\]
does that look nicer? :}

9x(7x+1/2)=3x+(1/2X)
lets say x=34
306238+1/2=102+1/234
68+1/2=68+1/2

lets say that x=113
1017791+1/2)=339+1/2113
226+1/2=226+1/2
i can do this all day, because X= ALL REAL NUMBERS

multiply both sides by 7x to get
\[4 = 84x + 28x\]
\[4 = 56x\]
\[0 = \frac{ 56x }{ 4 }\]
0 = 14x
0 = x

@lharrell97 if x=x then it can be anything because you don't know the value of x so it could be an imaginary number or it could be elephant...not JUST all real numbers

because you dont know the value of X, it could be any possible number. x could equal 3 billion or it could equal 2. the answer therefore is X= all real numbers... although i can see where you're coming from haha

look like that?
\[\frac{ x + 5 }{ 3 } =\frac{ x  3 }{ 4 }\]
