Solution for 2(5z-1)-3(z+6)=5(z+1) equation:


Simplifying
2(5z + -1) + -3(z + 6) = 5(z + 1)

Reorder the terms:
2(-1 + 5z) + -3(z + 6) = 5(z + 1)
(-1 * 2 + 5z * 2) + -3(z + 6) = 5(z + 1)
(-2 + 10z) + -3(z + 6) = 5(z + 1)

Reorder the terms:
-2 + 10z + -3(6 + z) = 5(z + 1)
-2 + 10z + (6 * -3 + z * -3) = 5(z + 1)
-2 + 10z + (-18 + -3z) = 5(z + 1)

Reorder the terms:
-2 + -18 + 10z + -3z = 5(z + 1)

Combine like terms: -2 + -18 = -20
-20 + 10z + -3z = 5(z + 1)

Combine like terms: 10z + -3z = 7z
-20 + 7z = 5(z + 1)

Reorder the terms:
-20 + 7z = 5(1 + z)
-20 + 7z = (1 * 5 + z * 5)
-20 + 7z = (5 + 5z)

Solving
-20 + 7z = 5 + 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.
-20 + 7z + -5z = 5 + 5z + -5z

Combine like terms: 7z + -5z = 2z
-20 + 2z = 5 + 5z + -5z

Combine like terms: 5z + -5z = 0
-20 + 2z = 5 + 0
-20 + 2z = 5
