Solution for 10[z-(7z+63)+3]=5(z+10) equation:


Simplifying
10[z + -1(7z + 63) + 3] = 5(z + 10)

Reorder the terms:
10[z + -1(63 + 7z) + 3] = 5(z + 10)
10[z + (63 * -1 + 7z * -1) + 3] = 5(z + 10)
10[z + (-63 + -7z) + 3] = 5(z + 10)

Reorder the terms:
10[-63 + 3 + z + -7z] = 5(z + 10)

Combine like terms: -63 + 3 = -60
10[-60 + z + -7z] = 5(z + 10)

Combine like terms: z + -7z = -6z
10[-60 + -6z] = 5(z + 10)
[-60 * 10 + -6z * 10] = 5(z + 10)
[-600 + -60z] = 5(z + 10)

Reorder the terms:
-600 + -60z = 5(10 + z)
-600 + -60z = (10 * 5 + z * 5)
-600 + -60z = (50 + 5z)

Solving
-600 + -60z = 50 + 5z

Solving for variable 'z'.

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

Add '-5z' to each side of the equation.
-600 + -60z + -5z = 50 + 5z + -5z

Combine like terms: -60z + -5z = -65z
-600 + -65z = 50 + 5z + -5z

Combine like terms: 5z + -5z = 0
-600 + -65z = 50 + 0
-600 + -65z = 50
