Question

найди корень каждого уравнения (x+56=60;90-x=45;x-60=100)

Answer 1

х + 56 = 60
х = 60 - 56
х = 4
----------------------------
90 - х = 45
х = 90 - 45
х = 45
-----------------------------
х - 60 = 100
х = 100 + 60
х = 160
----------------------------

Answer 2

x+56=60 
x=60-56
x=4 

90-x=45 
x =90-45
x=45

x-60=100 
x=100+60
x =160
