if x= 7 what is the value of x-4
7 - 4
=3
if y=3 what is the value of 8y
8 x 3
= 24
if x=7 what is the value of 3x-4
(3 x 7) - 4
= 17
if x=7 and y=3 what is the value of 2x-7y
(2 x 7) -(7 x 3)
= - 7
if x=7 and y=3 what is the value of 4y-X
(4 x 7) - 3
= 25
Hope this helps
Answer:
1st one a^-1 , 2nd one a^b/a^c , 3rd one a^c/b^c
(_ , _) means (X , Y)
(25 , ) means
X = 25 then you need find the value of Y from the equation .

so the first answer is (25,-3)
..............
( , -8) means
Y = -8 then you need to find the value of X from the equation .

so the second answer is ( 0 , -8 )
hope this would help you
