Question

5X + 3 = 3X + 7
12 - 2X = 10 las inecuaciones de igualdades
5X + 10 -5 = 15

Answer 1

Respuesta:

a) 5x + 3 = 3x + 7

x = 2

b) 12 - 2x = 10

x = 1

c) 5x + 10 - 5 = 15

x = 2

Explicación paso a paso:

a) 5x + 3 = 3x + 7

5x - 3x = -3 + 7

2x = +4 (o solo 4)

x = 4/2

x = 2

b) 12 - 2x = 10

-2x = 10 - 12

-2x = -2

x = -2/-2

x = 1

c) 5x + 10 - 5 = 15

5x + 5 = 15

5x = 15 - 5

5x = 10

x = 10/5

x = 2
