Question

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

Answer 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

=

10

−10

z=−1

Answer 2

Plus 5z from both sides
7=17 + 10z

Minus 17 from both sides

-10 = 10z
Z= -1
