Solution for 3(4z-1)-2(z+7)=5(z+1) equation:


Simplifying
3(4z + -1) + -2(z + 7) = 5(z + 1)

Reorder the terms:
3(-1 + 4z) + -2(z + 7) = 5(z + 1)
(-1 * 3 + 4z * 3) + -2(z + 7) = 5(z + 1)
(-3 + 12z) + -2(z + 7) = 5(z + 1)

Reorder the terms:
-3 + 12z + -2(7 + z) = 5(z + 1)
-3 + 12z + (7 * -2 + z * -2) = 5(z + 1)
-3 + 12z + (-14 + -2z) = 5(z + 1)

Reorder the terms:
-3 + -14 + 12z + -2z = 5(z + 1)

Combine like terms: -3 + -14 = -17
-17 + 12z + -2z = 5(z + 1)

Combine like terms: 12z + -2z = 10z
-17 + 10z = 5(z + 1)

Reorder the terms:
-17 + 10z = 5(1 + z)
-17 + 10z = (1 * 5 + z * 5)
-17 + 10z = (5 + 5z)
