Answer: SR = 42
Explanation:
8x-6 = 36 + x
subtract x
8x - x - 6 = 36 + x - x
(Note +x -x = 0, same goes to any number or variable.)
7x - 6 = 36
add 6
7x - 6 + 6 = 36 + 6
7x = 42
7x/7 = 42/7
x = 6
So far we found x, so now we would put x in SR which is 8x - 6
SR = 8x - 6
SR = 8(6) - 6
SR = 48 - 6
SR = 42.
Therefore SR is 42.
