Question

resuelve las siguientes ecuaciones lineales con una incógnita​

Answer 1

Explicación paso a paso:

•5x + 3 = 16

5x = 16-3

5x = 13

x = 13/5

x = 2,6

•2x = 36

x = 36/2

x = 18

•5x - 3 = 48

5x = 48 +3

5x = 51

x = 51 / 5

x = 10,2

•3x = -30

x = -30 / 3

x = -10

•-2x + 20 = -4x + 28

-2x + 4x = 28 - 20

2x = 8

x = 8/2

x = 4

•80 = 3.5x - 18

80 +18 = 3.5x

98 = 3.5 x

98 / 3.5 = x

28 = x
