Question

Solve : 5z/(3 )+ 3 =7+z​

Answer 1

Answer:

$\frac{5z}{3} + 3 = 7 + z \\ \\ = > \frac{5z + 9}{3} = 7 + z \\ \\ = > 5z + 9 = 3(7 + z) \\ \\ = > 5z + 9 = 21 + 3z \\ \\ = > 5z - 3z = 21 - 9 \\ \\ = > 2z = 12 \\ \\ = > z = \frac{12}{2} \\ \\ = > z = 6$

Answer 2

Step-by-step explanation:

3

5z

+3=7+z

=>

3

5z+9

=7+z

=>5z+9=3(7+z)

=>5z+9=21+3z

=>5z−3z=21−9

=>2z=12

=>z=
