Solution for 3(5z-1)-5(z+8)=8(z+1) equation:


Simplifying
3(5z + -1) + -5(z + 8) = 8(z + 1)

Reorder the terms:
3(-1 + 5z) + -5(z + 8) = 8(z + 1)
(-1 * 3 + 5z * 3) + -5(z + 8) = 8(z + 1)
(-3 + 15z) + -5(z + 8) = 8(z + 1)

Reorder the terms:
-3 + 15z + -5(8 + z) = 8(z + 1)
-3 + 15z + (8 * -5 + z * -5) = 8(z + 1)
-3 + 15z + (-40 + -5z) = 8(z + 1)

Reorder the terms:
-3 + -40 + 15z + -5z = 8(z + 1)

Combine like terms: -3 + -40 = -43
-43 + 15z + -5z = 8(z + 1)

Combine like terms: 15z + -5z = 10z
-43 + 10z = 8(z + 1)

Reorder the terms:
-43 + 10z = 8(1 + z)
-43 + 10z = (1 * 8 + z * 8)
-43 + 10z = (8 + 8z)
