Answer:
B & C (1/4x = 5 - x and 3/2x = 6)
Explanation:
Which of the following equations has a solution x = 4?
we solve all the equation
A)
1/x = 2
x = 1/2
-----------------
B)
1/4x = 5 - x
1/4x−{−x+5}=0
5/4x−5=0
(5/4)*x+(−5)=0
x=−(−5)/(5/4)
x= -(-5)/(5/4)
x = 4
------------------
C)
3/2x = 6
x = 6 * 2/3
x = 4
-----------------
D)
3/4x = 5
x = 5 : 3/4
x = 5 * 4/3
x = 20/3
