Exercise 21 Page 46

Start by factoring y out of the expression on the right-hand side of the equation.

y=a/9+3x

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 To begin, we will factor y out of the expression on the right-hand side of the equation.

a=9y+3yx

FactorOut

Factor out y

a=y(9+3x)

DivEqn

.LHS /(9+3x).=.RHS /(9+3x).

a/9+3x=y
