1 answer:
dmitriy555 [2]2 years ago

Answer: x= -2 and y=7

Step-by-step explanation:

4×20x+11y=37

20×4x+3y=13

Using elimination method

80x+44y=148

80x+60y=260

-16y/-16=-112/-16

Y=7

Substitute for Y in equation (1)

20x+ 11(7)=37

20x+77=37

20x=37-77

20x/20= -40/20

X= -2

therefore, x=-2 and y=7

*How does placing the Declaration of Independence in its historic context change its meaning?
Strike441 [17]

Answer:

Declaration of Independence was designed for multiple audiences: the King, the colonists, and the world. It was also designed to multitask. Its goals were to rally the troops, win foreign allies, and to announce the creation of a new country. The introductory sentence states the Declaration’s main purpose, to explain the colonists’ right to revolution. In other words, “to declare the causes which impel them to the separation.” Congress had to prove the legitimacy of its cause. It had just defied the most powerful nation on Earth. It needed to motivate foreign allies to join the fight.
