Question

maths class 7th simple equation lesson​

Answer 1

• x = 5
• x = -4
• b = 9+7 = 16
• y = 20-8 = 12
• p = -6-6 = -12
• t = -60/30 = -2
• r = -48
• a = -18/5

Answer 2

A:x-5=0

x=0+5

x=5

B:x+4=0

x=0+4

x=4

C: b-7=9

b=9+7

b=16

D: y+8=20

y=20-8

y=12

E: p+6= -6

p=-6-6

p=-12

F: 30t=-60

t=-60/30

t=-2

G: -r/8=6

-r=6×8

-r=48

h: -a/11=18/55

-a×55=18×11

-55a=198

-a=198/55

-a=3.6

Hope this helps...
