Solution for 3(5z-1)-5(z+1)=3(z+1) equation:


Simplifying
3(5z + -1) + -5(z + 1) = 3(z + 1)

Reorder the terms:
3(-1 + 5z) + -5(z + 1) = 3(z + 1)
(-1 * 3 + 5z * 3) + -5(z + 1) = 3(z + 1)
(-3 + 15z) + -5(z + 1) = 3(z + 1)

Reorder the terms:
-3 + 15z + -5(1 + z) = 3(z + 1)
-3 + 15z + (1 * -5 + z * -5) = 3(z + 1)
-3 + 15z + (-5 + -5z) = 3(z + 1)

Reorder the terms:
-3 + -5 + 15z + -5z = 3(z + 1)

Combine like terms: -3 + -5 = -8
-8 + 15z + -5z = 3(z + 1)

Combine like terms: 15z + -5z = 10z
-8 + 10z = 3(z + 1)

Reorder the terms:
-8 + 10z = 3(1 + z)
-8 + 10z = (1 * 3 + z * 3)
-8 + 10z = (3 + 3z)

Solving
-8 + 10z = 3 + 3z

Solving for variable 'z'.

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

Add '-3z' to each side of the equation.
-8 + 10z + -3z = 3 + 3z + -3z

Combine like terms: 10z + -3z = 7z
-8 + 7z = 3 + 3z + -3z

Combine like terms: 3z + -3z = 0
-8 + 7z = 3 + 0
-8 + 7z = 3

Add '8' to each side of the equation.
