No sean malos y ayudenme con estas escuaciones
3 (x + 2 ) = 4(x-1)+3
______
2
4 (x -6 ) + 2 ( x + 4) = 2x
______ ______
3 5

Answer 1

3x + 6 = 4x - 4 + 3

3x - 4x = - 6 - 4 + 3

- x = - 7

x = (-) (-7)

x = 7

--------------------
4x - 24 + 2x + 8 = 2x

4x + 2x - 2x = 24 - 8

4x = 16

x = 16 / 4

x = 4
