Question

Qual o valor dessa equação 5(z + 1) - 2(3z + 1) = 4(5 - z)

Answer 1

Oie, Td Bom?!

5(z + 1) - 2(3z + 1) = 4(5 - z)

5z + 5 - 6z - 2 = 4(5 - z)

- z + 3 = 20 - 4z

- z + 4z = 20 - 3

3z = 17

z = 17/3

Answer 2

5( z + 1 ) - 2( 3z + 1 ) = 4( 5 - z )

5z + 5 - 6z - 2 = 20 - 4z

-z + 3 = 20 - 4z

-z + 4z = 20 - 3

3z = 17

z = 17/3
