10(z-1)=50 when solving for x

To solve for x, let's first simplify the equation by distributing the 10 on the left side:

10z - 10 = 50

Next, let's isolate the variable by moving the constant term to the right side:

10z = 60

Finally, divide both sides by 10 to solve for z:

z = 6

Therefore, when solving for x, the solution is z = 6.
