-(2+4)=-2(z+3)

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

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

Combine like terms: 2 + 4 = 6
-1(6) = -2(z + 3)

Multiply -1 * 6
-6 = -2(z + 3)

Reorder the terms:
-6 = -2(3 + z)
-6 = (3 * -2 + z * -2)
-6 = (-6 + -2z)

Add '6' to each side of the equation.
-6 + 6 = -6 + 6 + -2z

Combine like terms: -6 + 6 = 0
0 = -6 + 6 + -2z

Combine like terms: -6 + 6 = 0
0 = 0 + -2z
0 = -2z

Solving
0 = -2z

Solving for variable 'z'.

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

Add '2z' to each side of the equation.
0 + 2z = -2z + 2z
Remove the zero:
2z = -2z + 2z

Combine like terms: -2z + 2z = 0
2z = 0

Divide each side by '2'.
z = 0

Simplifying
z = 0
