(a).v8=5+x (b). x-3=8 (c). x-5=7 (d) 3x-2=10
(e). 7x=49 (f). 9x=20-x (g). y/2=3​

Answer 1

Answer:

a)5+x=8

x=8-5

X=3

b)x-3=8

x=8+3

x=11

c)x-5=7

x=7+5

x=12

d)3x-2=10

3x=10+2=12

x=12/3=4

e)7x=49

x=49/7

X=7

f)9x=20-x

9x+x=20

10x=20

x=2

g)y/2=3

y=3*2=6

Answer 2

or,5+x=8

or, x=8-5

or,x=3

b)x-3=8

or, x=8+3

or,x=11

c) x-5=7

or,x=7+5

or,x=12

d)3x-2=10

or,3x=10+2

or,x=12/3

or,x=4

e)7x=49

or,x=49/7

or,x=7

f)9x=20-x

or,9x+x=20

or,10x=20

or,x=20/10

or,x=2

g) y/2=3

or, y=3×2

or,y=6
