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


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

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

Reorder the terms:
-5 + 10z + -2(2 + z) = 6(z + 1)
-5 + 10z + (2 * -2 + z * -2) = 6(z + 1)
-5 + 10z + (-4 + -2z) = 6(z + 1)

Reorder the terms:
-5 + -4 + 10z + -2z = 6(z + 1)

Combine like terms: -5 + -4 = -9
-9 + 10z + -2z = 6(z + 1)

Combine like terms: 10z + -2z = 8z
-9 + 8z = 6(z + 1)

Reorder the terms:
-9 + 8z = 6(1 + z)
-9 + 8z = (1 * 6 + z * 6)
-9 + 8z = (6 + 6z)

Solving
-9 + 8z = 6 + 6z

Solving for variable 'z'.

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

Add '-6z' to each side of the equation.
