The difference between two numbers, a and b, is 21. the difference of 5 times a and two times b is 18. what are the values of a and b?

  (a, b) = (-8, -29)

Step-by-step explanation:

The two relations can be written as the equations ...

  a - b = 21

  5a -2b = 18

Subtracting 2 times the first equation from the second, we have ...

  (5a -2b) -2(a -b) = (18) -2(21)

  3a = -24 . . . . . simplify

  a = -8 . . . . . . . divide by 3

Substituting into the first equation, we have ...

  -8 -b = 21

  -b = 29 . . . . . .  add 8

  b = -29 . . . . . . multiply by -1

The values of a and b are -8 and -29, respectively.

step-by-step explanation:

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.
