Answer
Attempt 1 out of 2
z, equalsz=
z = (57 - 7) / (-10) = -5
To solve for z, follow these steps:
Step 1: Subtract 7 from both sides of the equation:
57 - 7 = -10z
Step 2: Simplify the left side of the equation:
50 = -10z
Step 3: Divide both sides of the equation by -10:
50 / -10 = -10z / -10
Step 4: Simplify:
-5 = z
Therefore, z equals -5.
To solve for zz in the equation "57 = -10z + 7", you need to isolate the variable z on one side of the equation. Here's how you can do it step by step:
Step 1: Start with the equation: 57 = -10z + 7.
Step 2: Subtract 7 from both sides of the equation to isolate the term with z. This gives: 57 - 7 = -10z.
Step 3: Simplify the left side of the equation: 50 = -10z.
Step 4: Divide both sides of the equation by -10 to solve for z: 50 / -10 = -10z / -10.
Step 5: Simplify: -5 = z.
Therefore, the solution to the equation 57 = -10z + 7 is z = -5.
