<span>-3x + 2y = 2 eq (1)
7x - 3y = 7 eq (2)
Mutiply eq (1) by 3 and eq (2) by 2:
-9x + 6y = 6
14x - 6y = 14
Add th two new equations:
-9x + 14x = 6 + 14
=> 5x = 20
=> x = 20/5
=> x = 4
Now from eq (1)
-3(4) + 2y = 2
=> 2y = 2 + 12
=> 2y = 14
=> y = 14 / 2
=> y = 7
So the ordered pair is (4,7)
Answer: option B. (4,7)

Answer:
<h2>30.4</h2>
Step-by-step explanation:
sin x = 4.6/9.1
sin x = 0.5055
Thus , x = 30.4
:-)
You would split an uneven number in half, by multiplying the uneven number by 5, and adding a decimal in between the numbers. (i.e. 9 x 5 = 45 = 4.5) Hope this helps:)
