# How do you solve 59=x+90?

Apr 7, 2018

$59 = x + 90$

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-

$59 = \left(- 31 + 90\right)$

$59 = 59$

#### Explanation:

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

#### Explanation:

$59 = x + 90$

Subtracting 90 from both sides:

$59 - 90 = x + \cancel{90} - \cancel{90}$

$- 31 = x$

color(magenta)(x=-31
