Solution for 2(4z)-3(5z+2)=4[10-(z+1)] equation:


Simplifying
2(4z) + -3(5z + 2) = 4[10 + -1(z + 1)]

Remove parenthesis around (4z)
2 * 4z + -3(5z + 2) = 4[10 + -1(z + 1)]

Multiply 2 * 4
8z + -3(5z + 2) = 4[10 + -1(z + 1)]

Reorder the terms:
8z + -3(2 + 5z) = 4[10 + -1(z + 1)]
8z + (2 * -3 + 5z * -3) = 4[10 + -1(z + 1)]
8z + (-6 + -15z) = 4[10 + -1(z + 1)]

Reorder the terms:
-6 + 8z + -15z = 4[10 + -1(z + 1)]

Combine like terms: 8z + -15z = -7z
-6 + -7z = 4[10 + -1(z + 1)]

Reorder the terms:
-6 + -7z = 4[10 + -1(1 + z)]
-6 + -7z = 4[10 + (1 * -1 + z * -1)]
-6 + -7z = 4[10 + (-1 + -1z)]

Combine like terms: 10 + -1 = 9
-6 + -7z = 4[9 + -1z]
-6 + -7z = [9 * 4 + -1z * 4]
-6 + -7z = [36 + -4z]

Solving
-6 + -7z = 36 + -4z

Solving for variable 'z'.

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

Add '4z' to each side of the equation.
-6 + -7z + 4z = 36 + -4z + 4z

Combine like terms: -7z + 4z = -3z
-6 + -3z = 36 + -4z + 4z

Combine like terms: -4z + 4z = 0
-6 + -3z = 36 + 0
-6 + -3z = 36

Add '6' to each side of the equation.
-6 + 6 + -3z = 36 + 6

Combine like terms: -6 + 6 = 0
0 + -3z = 36 + 6
-3z = 36 + 6

Combine like terms: 36 + 6 = 42
-3z = 42

Divide each side by '-3'.
z = -14

Simplifying
z = -14
