Step-by-step explanation:
-7(1+3x) = 4 + 5x
-7 - 21x = 4 + 5x
(get all the variables on one side. Don't forget to change the signs)
-7-4 = 5x + 21x
-11 = 26x
(divide both sides by the coefficient [26])
26x/26= -11/26
x = -11/26
Y=k/x
2.5=k/6
k=15
wheny x=4, y=15/4
y=3.75
The correct answer is 2x-1
Answer:
I guess its 2/2.
