Answer:

1 . X=-6

2. -9b+6z-2

3. -6z+1

Step-by-step explanation:

1. Solve for  x  by simplifying both sides of the equation, then isolating the variable.

2. Combine like terms = combine -4b and -5b , combine 5z and z and then -2 is left alone

3. Subtract the numbers

12-11 = 1

Then combine like terms

-15z+9z = -6z
