23.600+x=50.000+300.
x+3.809-1.070=8.500.
2.038+5.655-x=2.836.
1.685+6.856=x+3.240+2.761.

Answer 1

23.600 + x = 50.000+300
x=50.300-23.600
x=26.700
x+3.809-1.070=8.500
x+2.739=8500
x=8500-2739
x=5761
2.038+5655-x=2836
7693-x=2836
7693-2836=x
x=4857
1.685+6856=x+3240+2761
8541=x+6001
x=8541-6001
x=2540

Answer 2

23.600+x=50.000+300.⇒23.600+x=50.300⇔x=50.300-23.600=26.700
x+3.809-1.070=8.500.⇔x+2739=8500⇔x=8500-2739⇔x=5761
2.038+5.655-x=2.836.⇔7693-x=2836⇒x=7693-2836=4857⇒x=4857
1.685+6.856=x+3.240+2.761.⇒8541=x+6001⇒x=8541-6001⇒x=2540
