Answer 1

Answer:

Step-by-step explanation:

a)-12=x+5

x=-12-5

x= -17

b)10=x+3

x=10-3

x=7

c)-x=-5+7

-x=2

(-x/-1)=(2/-1)

x=-2

d)3y=-18

y=-18/3

y=6

e)-7y=-28

(-7y/-7)=(-28/-27)

y=4

f)x/3=-2

x=-2(3)

x=-6

g)y/4=7

y=7(4)

y=28

h)8r/9 = 56

8r=56(9)

(8r/8)=(504/8)

r=63

I)13p/3 = 52

13p=52(3)

(13p/13)= 156/13

p=12
