Question

7z + 13 = 2z + 4 Solve the equation

Answer 1

7z+13=2z+4
7z-2z=4-13
5z=-9
z=-9/5

hope it helps:))

Answer 2

Answer:

$z = \frac{ - 9}{5}$

Step-by-step explanation:

The equation is linear equation in one variable.

To solve the equation, just put the terms with z on left hand side of the equation and constant terms on the right hand side of the equation.

$7z + 13 = 2z + 4 \\ \\ 7z - 2z = 4 - 13 \\ \\ 5z = - 9 \\ \\ z = \frac{ - 9}{5}$

Hope it helps you.

Note: Don't forget to change the sign of that digits while taking from RHS to LHS and vice versa.
