You don’t need a number just an expression to find the variable

Solve for y. Note the equal sign. What you do to one side, you do to the other. Isolate the y. Do the opposite of PEMDAS.

First, subtract x from both sides

y²z + x (-x) = b (-x)

y²z = b - x

Next, divide z from both sides

(y²z)/z = (b - x)/z

y² = (b - x)/z

Finally, to fully isolate the x, root both sides

√(y²) = √((b - x)/z)

y = √((b - x)/z)

y = √((b - x)/z) is your answer
