Solution for (z+2)*2+(z-3)*2=2(z+4)*2-1 equation:


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

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

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

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

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

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

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

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

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

Reorder the terms for easier multiplication:
-2 + 4z = 2 * 2(4 + z) + -1

Multiply 2 * 2
-2 + 4z = 4(4 + z) + -1
-2 + 4z = (4 * 4 + z * 4) + -1
-2 + 4z = (16 + 4z) + -1

Reorder the terms:
-2 + 4z = 16 + -1 + 4z

Combine like terms: 16 + -1 = 15
-2 + 4z = 15 + 4z

Add '-4z' to each side of the equation.
-2 + 4z + -4z = 15 + 4z + -4z

Combine like terms: 4z + -4z = 0
-2 + 0 = 15 + 4z + -4z
-2 = 15 + 4z + -4z

Combine like terms: 4z + -4z = 0
-2 = 15 + 0
-2 = 15

Solving
-2 = 15
