Question

a)2x = 6
b) 2x - 3 = 6 + x
c) 4 (x - 10) = -6 (2 - x) - 6X

explicacion en ecuaciones!!!

Answer 1

Respuesta:

2 x = 6

x = 6 - 2

x = 4

2 x - 3 = 6 + x

2 x - 3 - x = 6

2 x - x = 6 + 3

x = 9

4 (x - 10) = -6 (2 - x) - 6x

4x - 40 = -12 + 6x - 6x

4x - 40 = -12

4x = -12 + 40

4x = 28

x = 28 : 4

x = 7
