Add 7

e/12=10

Multiply by 12

e=120

6b. n/3+12=27

Subtract 12

n/3=15

Multiply by 3

n=45

7b. 6x+25=73

Subtract 25

6x=48

Divide by 6

x=8

8b. x/7+14=22

Subtract 14

Multiply by 7

x=56

9b. a/6+4=20

Subtract 4

a/6=16

Multiply by 6

a=96

1c. b/4+2=11

Subtract 2

b/4=9

Multiply by 4

b=36

2c. r/20-3=3

Add 3

r/20=6

Multiply by 20

r=120

Divide by 5

m=11

9c. 3p-15=48

Add 15

3p=63

Divide by 3

p=21

One or two may be wrong but that's because I was trying to do the answers quickly.

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
