Exercise 22 Page 129

Apply inverse operations to isolate a.

a=- y-z/x-w

Practice makes perfect

To solve the given literal equation for a, we will use the Properties of Equality to apply inverse operations on the equation. Remember, only like terms can be combined.

ax+z=aw-y

LHS-aw=RHS-aw

ax+z-aw=- y

LHS-z=RHS-z

ax-aw=- y-z

SplitIntoFactors

Split into factors

a* x-a* w=- y-z

Factor out a

a(x-w)=- y-z

.LHS /(x-w).=.RHS /(x-w).

a=- y-z/x-w
