Exercise 12 Page 40

Apply inverse operations to isolate y.

y=16-12x

Practice makes perfect

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

11-1/2y=3+6x

SubEqn

LHS-11=RHS-11

- 1/2y=- 8 + 6x

MoveRightFacToNum

a/c* b = a* b/c

- y/2=- 8+6x

MoveNegFracToDenom

Put minus sign in denominator

y/- 2=-8+6x

Now we can eliminate the fraction by multiplying both sides of the equation by - 2.

y/- 2=-8+6x
