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


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

Reorder the terms:
3(-1 + 5z) + -5(z + 2) = 2(z + 1)
(-1 * 3 + 5z * 3) + -5(z + 2) = 2(z + 1)
(-3 + 15z) + -5(z + 2) = 2(z + 1)

Reorder the terms:
-3 + 15z + -5(2 + z) = 2(z + 1)
-3 + 15z + (2 * -5 + z * -5) = 2(z + 1)
-3 + 15z + (-10 + -5z) = 2(z + 1)

Reorder the terms:
-3 + -10 + 15z + -5z = 2(z + 1)

Combine like terms: -3 + -10 = -13
-13 + 15z + -5z = 2(z + 1)

Combine like terms: 15z + -5z = 10z
-13 + 10z = 2(z + 1)

Reorder the terms:
-13 + 10z = 2(1 + z)
-13 + 10z = (1 * 2 + z * 2)
-13 + 10z = (2 + 2z)
