Solution for 3(6z-1)-4(z+5)=7(z+1) equation:


Simplifying
3(6z + -1) + -4(z + 5) = 7(z + 1)

Reorder the terms:
3(-1 + 6z) + -4(z + 5) = 7(z + 1)
(-1 * 3 + 6z * 3) + -4(z + 5) = 7(z + 1)
(-3 + 18z) + -4(z + 5) = 7(z + 1)

Reorder the terms:
-3 + 18z + -4(5 + z) = 7(z + 1)
-3 + 18z + (5 * -4 + z * -4) = 7(z + 1)
-3 + 18z + (-20 + -4z) = 7(z + 1)

Reorder the terms:
-3 + -20 + 18z + -4z = 7(z + 1)

Combine like terms: -3 + -20 = -23
-23 + 18z + -4z = 7(z + 1)

Combine like terms: 18z + -4z = 14z
-23 + 14z = 7(z + 1)

Reorder the terms:
-23 + 14z = 7(1 + z)
-23 + 14z = (1 * 7 + z * 7)
-23 + 14z = (7 + 7z)
