Question

2300+12*(2016-1963/x)=45380

Answer 1

2300+12*(2016-1963/x)=45380
2300+24192-23556/х=45380
26492-23556/х=45380
-23556/х=45380-26492
-23556/х=18888
х=-23556/18888
х=-1,247

Answer 2

$23000+12*(2016- frac{1963}{x} )=45380, 12*(2016- frac{1963}{x} )=45380-23000$
$12*(2016- frac{1963}{x} )=22380, 2016- frac{1963}{x} =22380:12$
$2016- frac{1963}{x} =1865$
$frac{1963}{x} =2016-1865$
$frac{1963}{x} =151$
$x= frac{1963}{151} x=13$
