Given the system of linear equations.
-x+y =7
6x+y=14
part a: use substitution to find the solution to the systems of equations. include all of your work in your final answer.
part b: algebraically verify your answer to part a. include all of your work in your final answer.

x=-1, y=8

Step-by-step explanation:

The given system is

-x+y =7

6x+y=14

We make y the subject in the first equation to get:

y=x+7

We put y=x+7 into 6x+y=14 to obtain

6x+x=14-7

7x=7

x=1

We now put x=1 into y=x+7

The solution is x=1, y=8

Part B

We now verify

-1+8=7 ....True

6(1)+8=14....True

the correct answer is a) "catholic church".

the proposals that liberals in mexico made during 1855 were particularly focused on a person's individual rights, such as the freedom of speech, the freedom of conscience, freedom of assembly, and the right to possess weapons.

when the constitution was formally published 2 years later (1857). it also contained an article which permitted education free from any religious influence, the removal of the catholic church institutional privileges, and the sale of property belonging to the church. all of these provisions were clearly against the catholic church interests.
