does y=11-x ,for x makje x=y+11?

-8-14=6

7.4=x-13 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=x-13

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.
