$59=x+90$

Transposition of $90$ to the other side of the equation!

$x=59-90$

Subtract the values!

$x= -31$

Voila!

If you want to double check-

$59=(-31+90)$

$59=59$

Tadaa!

Due to the rules of Linear equations, while the number 90 is transposed to the other side of the equation, it changes its value from $+$ to $-$ !

$color(magenta)(x=-31$

$59=x+90$

Subtracting 90 from both sides:

$59-90=x+cancel90-cancel90$

$-31=x$

$color(magenta)(x=-31$

~Hope this helps! :)
