SOLVING SYSTEMS OF EQUATIONS ALGEBRAICALLY BY ELIMINATION/ ADDITION In 1-6, solve and check each system of equations algebraically using addition/ elimination.

3. solve by graphing: y = 2x + 6 x + y = -3

Will give are given that xy is parallel to zw. if xz is a transversal that intercepts xy and zw, angle angle alternate interior angles. since xy is parallel to zw, we know that these angles are we also know that angle xvy and angle zvw are , and thus congruent. we can conclude that △xyv ~ △zwv using the similarity theorem.

Me! last question, and i'm stuck! write the algebraic expression that models the word phrase. the product of 2 divided by the number h and 8 more than the number k
