does y=11x ,for x makje x=y+11?
814=6
7.4=x13 answer 6.1
m/m for m =72 and n =9 m/n=72/9=8
4x+7=39 4x/4x=32/4x 4/32=x8
10 is greater than 18
4*(9)= 36

Subtract 11 from both sides.
y 11 = x
Multiply both sides by 1.
11  y = x
8  14 = 22 ≠ 6
7.4=x13
Add 13 to both sides.
20.4 = x (I don't know how you got 6.1.)
m/n=72/9=8 (Yes!)
4x+7=39
First, subtract 7 from both sides.
4x = 32
Then divide both sides by 4.
x = 32/4 = 8
Last two are correct. However, with the parentheses, your asterisk (*) to indicate multiplication is redundant.
