The answer to this question is D
Answer: 10
Step-by-step explanation:
My answer is correct because, if x=5 then were just multiplying 2 times 5 since 5 is not on the top like
because if it was that means we have to multiply 2 by itself 5 times. But since its not a exponent you just multiply 2 times 5. And 2 x 5= 10.
Hope This Helps!
Lets say two numbers are x and y
x+y=70-----------------------eq1
x=4y--------------------eq2
4y+y=70
5y=70
y=70/5
y=14
then x=4*14
x=56
