Answer:
x= 10, y= 6
Step-by-step explanation:
2x -3y= 2 -----(1)
-2x -y= -26 -----(2)
(1) +(2):
2x -3y -2x -y= 2 -26
-4y= -24
y= -24 ÷(-4)
y= 6
Substitute y= 6 into (1):
2x -3(6)= 2
2x -18= 2
2x= 18 +2
2x= 20
Divide both sides by 2:
x= 20 ÷2
x= 10

Answer:
<h3>40 degrees</h3>
Step-by-step explanation:
If the temperature dropped 5 degrees every hour, this can be expressed as;
5 degree = 1 hour
To get the total number of degree dropped fro 8hours, we will say;
x degree = 8hours where x is the temperature drop in all
Solving both equality
5 degree = 1 hour
x degree = 8 hours
cross multiply
x * 1 = 5 * 8
x = 40 degrees
<em>Hence the total temperature drop in all is 40°</em>
Answer:
<u>Step 1: Solve for x in the first equation</u>

Since you divide by a negative, you must flip the sign.
