Solution for 4(6z-1)-4(z+2)=7(2+1) equation:


Simplifying
4(6z + -1) + -4(z + 2) = 7(2 + 1)

Reorder the terms:
4(-1 + 6z) + -4(z + 2) = 7(2 + 1)
(-1 * 4 + 6z * 4) + -4(z + 2) = 7(2 + 1)
(-4 + 24z) + -4(z + 2) = 7(2 + 1)

Reorder the terms:
-4 + 24z + -4(2 + z) = 7(2 + 1)
-4 + 24z + (2 * -4 + z * -4) = 7(2 + 1)
-4 + 24z + (-8 + -4z) = 7(2 + 1)

Reorder the terms:
-4 + -8 + 24z + -4z = 7(2 + 1)
