Please look in your text book for this problem Statement    Elimination Method:

The equations are Equation (1) Equation (2)

Since the coefficients of b-terms are additive inverses, these terms can be

elimanted by adding equations.

Write the equations in clumn form and add the corresponding columns.  According to division property of equality: Divide each side by 3.  (Cancel common terms). Now, find the b value by substituting in either equation. (Equation 1). (Product of two different signs is negative) According to addition property of equality: Add 2 to each side.  (Apply commutative property of addition: ) (Apply additive inverse property: ) (Apply additive identity property: ) (Add: ) According to division property of equality: Divide each side by 3.  (Cancel common terms) (Multiply each side by negative one) (Product of two same signs is positive) The solution is . TESTIMONIALS
