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

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

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

Reorder the terms:
-1(4 + z) = -2(z + 3)
(4 * -1 + z * -1) = -2(z + 3)
(-4 + -1z) = -2(z + 3)

Reorder the terms:
-4 + -1z = -2(3 + z)
-4 + -1z = (3 * -2 + z * -2)
-4 + -1z = (-6 + -2z)

Solving
-4 + -1z = -6 + -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.
-4 + -1z + 2z = -6 + -2z + 2z

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

Combine like terms: -2z + 2z = 0
-4 + 1z = -6 + 0
-4 + 1z = -6

Add '4' to each side of the equation.
-4 + 4 + 1z = -6 + 4

Combine like terms: -4 + 4 = 0
0 + 1z = -6 + 4
1z = -6 + 4

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

Divide each side by '1'.
z = -2

Simplifying
z = -2
