- If 4 (x – y) = 64 and 4 (x + y) = 1024, then find the value of x.
Question 1:
If 4 (x – y) = 64 and 4 (x + y) = 1024, then find the value of x. A. 3
B. 1
C. 6
D. 4
Feedback 4 (x – y) = 64
4^(x – y) = 64 = 4^3
Equation 1) x – y = 3
4^(x + y) = 1024 = 4^5
Equation 2) x + y = 5
Solving equation (1) and (2), we get
x = 4 and y = 1
4^(x – y) = 64 = 4^3
Equation 1) x – y = 3
4^(x + y) = 1024 = 4^5
Equation 2) x + y = 5
Solving equation (1) and (2), we get
x = 4 and y = 1
