Solution for 9(2z+7)-7(z+3)=8(7-3z)-2(6z+7) equation:


Simplifying
9(2z + 7) + -7(z + 3) = 8(7 + -3z) + -2(6z + 7)

Reorder the terms:
9(7 + 2z) + -7(z + 3) = 8(7 + -3z) + -2(6z + 7)
(7 * 9 + 2z * 9) + -7(z + 3) = 8(7 + -3z) + -2(6z + 7)
(63 + 18z) + -7(z + 3) = 8(7 + -3z) + -2(6z + 7)

Reorder the terms:
63 + 18z + -7(3 + z) = 8(7 + -3z) + -2(6z + 7)
63 + 18z + (3 * -7 + z * -7) = 8(7 + -3z) + -2(6z + 7)
63 + 18z + (-21 + -7z) = 8(7 + -3z) + -2(6z + 7)

Reorder the terms:
63 + -21 + 18z + -7z = 8(7 + -3z) + -2(6z + 7)

Combine like terms: 63 + -21 = 42
42 + 18z + -7z = 8(7 + -3z) + -2(6z + 7)

Combine like terms: 18z + -7z = 11z
42 + 11z = 8(7 + -3z) + -2(6z + 7)
42 + 11z = (7 * 8 + -3z * 8) + -2(6z + 7)
42 + 11z = (56 + -24z) + -2(6z + 7)

Reorder the terms:
42 + 11z = 56 + -24z + -2(7 + 6z)
42 + 11z = 56 + -24z + (7 * -2 + 6z * -2)
42 + 11z = 56 + -24z + (-14 + -12z)

Reorder the terms:
42 + 11z = 56 + -14 + -24z + -12z

Combine like terms: 56 + -14 = 42
42 + 11z = 42 + -24z + -12z

Combine like terms: -24z + -12z = -36z
42 + 11z = 42 + -36z

Add '-42' to each side of the equation.
42 + -42 + 11z = 42 + -42 + -36z

Combine like terms: 42 + -42 = 0
0 + 11z = 42 + -42 + -36z
11z = 42 + -42 + -36z

Combine like terms: 42 + -42 = 0
11z = 0 + -36z
11z = -36z

Solving
11z = -36z

Solving for variable 'z'.

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

Add '36z' to each side of the equation.
11z + 36z = -36z + 36z

Combine like terms: 11z + 36z = 47z
47z = -36z + 36z

Combine like terms: -36z + 36z = 0
47z = 0

Divide each side by '47'.
z = 0

Simplifying
z = 0
