Solution for 2(6z-1)-5(z+1)=4(z+1) equation:


Simplifying
2(6z + -1) + -5(z + 1) = 4(z + 1)

Reorder the terms:
2(-1 + 6z) + -5(z + 1) = 4(z + 1)
(-1 * 2 + 6z * 2) + -5(z + 1) = 4(z + 1)
(-2 + 12z) + -5(z + 1) = 4(z + 1)

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

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

Combine like terms: -2 + -5 = -7
-7 + 12z + -5z = 4(z + 1)

Combine like terms: 12z + -5z = 7z
-7 + 7z = 4(z + 1)
