Question

Resolver las siguientes ecuaciones calculando el valor de la incognita


a) x+3+10=28
b)3x+10=40
c)x:2-33=124

Answer 1

x + 3 + 10 = 28

x + 13 = 28

x = 28 - 13

x = 15
---------------------------------

3x + 10 = 40

3x = 40 - 10

3x = 30

x = 30/3

x = 10
-----------------------------

x/2 - 33 = 124

x/2 = 124 + 33

x/2 = 157

x = 2 (157)

x = 314
