obtain 3
e) 14 less than half a number is 7.
D 2 added to the product of a number and
4 gives 26.​

Answer 1

1) 4+y=9

2) a: x+3=12

b: x-7=2

c: 2x+8=6

d: 6-x=3

Answer 2

Step-by-step explanation:

1. 4)4+y=9

2. a) let the number be X

ATQ--

3+X=12

or,X=12-3

or,X=9

b) let the number be X

ATQ--

X-7=2

or,X=2+7

or,X=9

d) let the number be X

ATQ--

6-X=3

or,-X=3-6

or,-X=-3

or,X=1+(-3)

or,X=1-3

or,X=-2

e) let the number be X

ATQ--

1X/2 - 14 =7

or,1X/2=7+14

or,1X/2=21

or,1X=21×2

or,1X=42

or,X=42/1

or,X=42
