Answer:
Step-by-step explanation:
5. x/7 = 9/x
x^2 = 63
x= 3
6. x/84 = 16/x
x^2 = 1344
x=8
7. x/12 = 12/16
16x=144
x=9
8. x/48 = 48/64
64x=2304
x=36
I got 60 as my answer
you ALWAYS do your parentheses first
then you do 8+5 and that equals 13•6-9
13 times 6 is 78. then you subtract 9 which will leave you with 60. hope that helped ☺️

This the only option to find x since doing the other way like 3x + 2 = 3x + 2 gives it an infinite solution.
4x - 1 = 3x + 2
-3x -3x
1x - 1 = 2
+1 +1
1x = 3

1 1
x = 3
Check:
4(3) - 1 = 3(3) + 2
12 - 1 = 9 + 2
11 = 11
