The solution is (5,2)
Step-by-step explanation:
From the third column the equation for sum of equivalent system is given as;
8x = 40
divide both sides by 8 to get value of x
8x/8 = 40/8
x=5
Using the value of x in the fifth column's first equation will be;
4x +4y =28
4(5) + 4y =28
20 +4y =28
4y= 28-20
4y=8
divide both sides by 4 to get y
4y/4 =8/4
y=2
The solution is x=5 and y=2 written as (5,2)

Answer:
36
Step-by-step explanation:
Add $9.40 two times what ever you get multiply that 15 and there’s your answer
Quadrant 2.
This is because the x-value is negative, and therefore is on the left side of the axis; and the y-value is positive, and therefore is on the top side of the axis. Putting this together, we find that (-2.7) is in Quadrant 2.
