Solution for 7[z-(5z+20)+8]=5(z+3) equation:


Simplifying
7[z + -1(5z + 20) + 8] = 5(z + 3)

Reorder the terms:
7[z + -1(20 + 5z) + 8] = 5(z + 3)
7[z + (20 * -1 + 5z * -1) + 8] = 5(z + 3)
7[z + (-20 + -5z) + 8] = 5(z + 3)

Reorder the terms:
7[-20 + 8 + z + -5z] = 5(z + 3)

Combine like terms: -20 + 8 = -12
7[-12 + z + -5z] = 5(z + 3)

Combine like terms: z + -5z = -4z
7[-12 + -4z] = 5(z + 3)
[-12 * 7 + -4z * 7] = 5(z + 3)
[-84 + -28z] = 5(z + 3)
