Question

Aflați pe x din egalitatile:x+45=5.27
X-39:3=471
5.x=74+59
X+57=72
X-46=376

Answer 1

x + 45 = 5.27

x = 5.27 - 45

x = - 39.73

--------------------------

x - 39 : 3 = 471

x - 13 = 471

x = 471 + 13

x = 484

--------------------------

5x = 74 + 59

5x = 133

x = 133/5

-------------------------

x + 57 = 72

x = 72 - 57

x = 15

-----------------------------

x - 46 = 376

x = 376 + 46

x = 422

------------------------------
