Exercise 20 Page 463

Multiply both sides of the equation by the reciprocal of 47.

v = 91/6

Practice makes perfect

To solve an equation, we should isolate the variable term. In this case, we will use the Multiplication Property of Equality and multiply both sides of the equation by the reciprocal of 47.

- 4/7v = - 8 23

MultEqn

LHS * (- 1)=RHS* (- 1)

- 4/7v* (- 1) = - 8 23* (- 1)

MultNegNegOnePar

- a(- b)=a* b

4/7v = 8 23

MultEqn

LHS * 7/4=RHS* 7/4

4/7v * 7/4 = 8 23 * 7/4
