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


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

Reorder the terms:
2(-1 + 5z) + -5(z + 4) = 3(z + 1)
(-1 * 2 + 5z * 2) + -5(z + 4) = 3(z + 1)
(-2 + 10z) + -5(z + 4) = 3(z + 1)

Reorder the terms:
-2 + 10z + -5(4 + z) = 3(z + 1)
-2 + 10z + (4 * -5 + z * -5) = 3(z + 1)
-2 + 10z + (-20 + -5z) = 3(z + 1)

Reorder the terms:
-2 + -20 + 10z + -5z = 3(z + 1)

Combine like terms: -2 + -20 = -22
-22 + 10z + -5z = 3(z + 1)

Combine like terms: 10z + -5z = 5z
-22 + 5z = 3(z + 1)

Reorder the terms:
-22 + 5z = 3(1 + z)
-22 + 5z = (1 * 3 + z * 3)
-22 + 5z = (3 + 3z)

Solving
-22 + 5z = 3 + 3z

Solving for variable 'z'.

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