100=15*(6.6+-0.06666666667z)+y+z

Solution for 100=15*(6.6+-0.06666666667z)+y+z equation:

Simplifying
100 = 15(6.6 + -0.06666666667z) + y + z
100 = (6.6 * 15 + -0.06666666667z * 15) + y + z
100 = (99 + -1z) + y + z

Reorder the terms:
100 = 99 + y + -1z + z

Combine like terms: -1z + z = 0
100 = 99 + y + 0
100 = 99 + y

Solving
100 = 99 + y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-1y' to each side of the equation.
100 + -1y = 99 + y + -1y

Combine like terms: y + -1y = 0
100 + -1y = 99 + 0
100 + -1y = 99

Add '-100' to each side of the equation.
100 + -100 + -1y = 99 + -100

Combine like terms: 100 + -100 = 0
0 + -1y = 99 + -100
-1y = 99 + -100

Combine like terms: 99 + -100 = -1
-1y = -1

Divide each side by '-1'.
y = 1

Simplifying
y = 1
