Solution for 5(2z-1)-2(z-9)=5(z+1) equation:


Simplifying
5(2z + -1) + -2(z + -9) = 5(z + 1)

Reorder the terms:
5(-1 + 2z) + -2(z + -9) = 5(z + 1)
(-1 * 5 + 2z * 5) + -2(z + -9) = 5(z + 1)
(-5 + 10z) + -2(z + -9) = 5(z + 1)

Reorder the terms:
-5 + 10z + -2(-9 + z) = 5(z + 1)
-5 + 10z + (-9 * -2 + z * -2) = 5(z + 1)
-5 + 10z + (18 + -2z) = 5(z + 1)

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

Combine like terms: -5 + 18 = 13
13 + 10z + -2z = 5(z + 1)

Combine like terms: 10z + -2z = 8z
13 + 8z = 5(z + 1)

Reorder the terms:
13 + 8z = 5(1 + z)
13 + 8z = (1 * 5 + z * 5)
13 + 8z = (5 + 5z)

Solving
13 + 8z = 5 + 5z

Solving for variable 'z'.

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