What would you need to multiply by in order to solve this system of equations using the linear combination (elimination) method?

6x-2y=4
7x+5y=3

a) multiply the 1st equation by 3 and leave the 2nd equation alone. this will eliminate the y's when you add the two new equations together.

b) multiply the 2nd equation by -6 and leave the 1st equation alone. this will eliminate the x's when you add the two new equations together.

c) multiply the 1st equation by 7 and multiply the 2nd equation by 4. this will eliminate the x's when you add the two new equations together.

d) multiply the 1st equation by 5 and multiply the 2nd equation by 2. this will eliminate the y's when you add the two new equations together.

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
