Solve for the variable by using the Cross Products Property.
4
To solve the proportion, we will start by using the Cross Products Property. Remember that we will need to treat -3(a-2) as a single quantity in the cross multiplication process.
Cross multiply
a(- b)=- a * b
Multiply
From here, we will continue solving for a by using the Distributive Property and the Properties of Equality.
Distribute -12
LHS+12a=RHS+12a
.LHS /6.=.RHS /6.
