Answer:

(2 , 5)

Step-by-step explanation:

Step 1: Subtract to eliminate x and solve for y

4x - 3y = -7

- 4x + y= 13

----------------

-4y = -20

y = 5

Step 2. Plug in the value of y into one of the equations and solve for x.

4x - 3y = -7

4x - 3(5) = -7

4x - 15 = -7

4x = 8

x = 2

Archy [21]

The converse of any statement, true or false, is never always true. The only guaranteed true statement is a contrapositive of a true statement. A contrapositive is a statement where the hypothesis and conclusion are switched, and both sides are negated.
