ANSWER
x=3, y=-4
EXPLANATION
The given system is :
First equation:

Second equation:

Let us multiply the first equation by 7 to get,
Third equation;

Let us multiply the second equation too by 10 to get,
Fourth equation:

Subtract the fourth equation from the third equation:


Divide both sides by 59.

Put y=-4 into the second equation and solve for x.





The solution is x=3, y=-4
Answer:
If a triangle is equilateral, then it must also be equiangular and vice versa.
Step-by-step explanation:
A biconditional statement denotes that both a statement AND its reciprocal statement must be true.
Given the two statements:
If a triangle is equilateral, then it must also be equiangular
and
If a triangle is equiangular, then it must also be equilateral.
As both of these statements are always true, we can combine them into one biconditional statement (meaning two conditions are met)
If a triangle is equilateral, then it must also be equiangular and vice versa.
True. it can only be written as one repeating number because eventually, a set of numbers would cancel out i think
