Solution for 5(2z+-1)+-2(z+9)=4(z+1) equation:


Simplifying
5(2z + -1) + -2(z + 9) = 4(z + 1)

Reorder the terms:
5(-1 + 2z) + -2(z + 9) = 4(z + 1)
(-1 * 5 + 2z * 5) + -2(z + 9) = 4(z + 1)
(-5 + 10z) + -2(z + 9) = 4(z + 1)

Reorder the terms:
-5 + 10z + -2(9 + z) = 4(z + 1)
-5 + 10z + (9 * -2 + z * -2) = 4(z + 1)
-5 + 10z + (-18 + -2z) = 4(z + 1)

Reorder the terms:
-5 + -18 + 10z + -2z = 4(z + 1)

Combine like terms: -5 + -18 = -23
-23 + 10z + -2z = 4(z + 1)

Combine like terms: 10z + -2z = 8z
-23 + 8z = 4(z + 1)

Reorder the terms:
-23 + 8z = 4(1 + z)
-23 + 8z = (1 * 4 + z * 4)
-23 + 8z = (4 + 4z)

Solving
-23 + 8z = 4 + 4z

Solving for variable 'z'.

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