2(5z-1)-2(z+7)=3(z+1)

Solution for 2(5z-1)-2(z+7)=3(z+1) equation:

Simplifying
2(5z + -1) + -2(z + 7) = 3(z + 1)

Reorder the terms:
2(-1 + 5z) + -2(z + 7) = 3(z + 1)
(-1 * 2 + 5z * 2) + -2(z + 7) = 3(z + 1)
(-2 + 10z) + -2(z + 7) = 3(z + 1)

Reorder the terms:
-2 + 10z + -2(7 + z) = 3(z + 1)
-2 + 10z + (7 * -2 + z * -2) = 3(z + 1)
-2 + 10z + (-14 + -2z) = 3(z + 1)

Reorder the terms:
-2 + -14 + 10z + -2z = 3(z + 1)

Combine like terms: -2 + -14 = -16
-16 + 10z + -2z = 3(z + 1)

Combine like terms: 10z + -2z = 8z
-16 + 8z = 3(z + 1)

Reorder the terms:
-16 + 8z = 3(1 + z)
-16 + 8z = (1 * 3 + z * 3)
-16 + 8z = (3 + 3z)

Solving
-16 + 8z = 3 + 3z

Solving for variable 'z'.

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

Add '-3z' to each side of the equation.
-16 + 8z + -3z = 3 + 3z + -3z

Combine like terms: 8z + -3z = 5z
-16 + 5z = 3 + 3z + -3z

Combine like terms: 3z + -3z = 0
-16 + 5z = 3 + 0
-16 + 5z = 3

Add '16' to each side of the equation.
-16 + 16 + 5z = 3 + 16

Combine like terms: -16 + 16 = 0
0 + 5z = 3 + 16
5z = 3 + 16

Combine like terms: 3 + 16 = 19
5z = 19

Divide each side by '5'.
z = 3.8

Simplifying
z = 3.8
