# How do you solve x+ x + 13.50= 25.50?

Nov 9, 2017

First, make the decimals as brackets, because we are not calculators
$x + x + \frac{1350}{100} = \frac{2550}{100}$
Solve the variables and transfer the fraction in LHS
$2 x = \frac{2550}{1000} - \frac{1350}{1000}$
Solve
$2 x = \frac{1200}{1000}$
That is equal to
$2 x = 12.00$
Transfer 2 to RHS
$x = \frac{12}{2}$
Solve
$x = 6$
