Question

Solve for zz.
57, equals, minus, 10, z, plus, 7
57=
−10z+7

Answer 1

To solve for z, we need to isolate the variable z on one side of the equation. We can do this by subtracting 7 from both sides of the equation:

57 - 7 = -10z + 7 - 7

This simplifies to:

50 = -10z

Now, we can solve for z by dividing both sides of the equation by -10:

50 / -10 = -10z / -10

This simplifies to:

-5 = z

Therefore, z equals -5.
