Question

27=1245+15x/43+x find x

Answer 1

the equation is:

$27=1245+\frac{15x}{43}+x$

so we can pass 1245 to the other side as "-1245" and sum the numbers with x, so 15/43+1=58/43

$\begin{gathered} 27-1245=(\frac{15}{43}+1)x \\ -1218=\frac{58}{43}x \end{gathered}$

and finally, we can pass the 43 multiplying and the 58 dividings:

$-1218\cdot\frac{43}{58}=x=-903$

So the answer is:

x=-903
