How do you solve 7-5z=17+5z

Plus 5z from both sides

7=17 + 10z

Minus 17 from both sides

-10 = 10z

Z = - 1

7-5z=17+5z

Step 1: Simplify both sides of the equation.

7-5z=17+5z

7+-5z=17+5z

-5z+7=5z+17

Step 2: Subtract 5z from both sides.

-5z+7-5z=5z+17-5z

-10z+7=17

Step 3: Subtract 7 from both sides.

-10z+7-7=17-7

-10z=10

Step 4: Divide both sides by - 10.

-10z

-10

=
