Answer:
Yes, the (–5, 0.5) is the solution set of the system.
Step-by-step explanation:
Given that:
x – 4y = –7 ------------- eq1
0.2x + 2y = 0 ----------- eq2
Now we have to check that, (–5, 0.5) is the solution of given system or not.
So from the given solution set:
x = -5
y = 0.5
Putting these values in eq1:
-5 - 4(0.5) = -7
By simplifying,
-5 - 2 = -7
-7 = -7 (satisfied)
Now putting the values of x and y in eq2:
0.2(-5) + 2(0.5)=0
By simplifying,
-1 +1 = 0
0 = 0 (satisfied)
i hope it will help you!
