Answer 1

Answer:

Ans1= 7+5x =37

5x =37-7

5x=30

x=30÷5

x=6

ans2= 3x+4=49

3x= 49-4

3x=45

x=45÷3

x=15

ans3= 2x+7=87

2x=87-7

2x=80

x=80÷2

x=40

ans4= 2b+b+b=180

4b=180

b=180÷4

b=45

Answer 2

Answer:

1. irfan marbles = 5*parmits marbles + 7

37 = 5m + 7

5m = 30

then,

m = 6

there fore parmit have 6 marbles

2. fathers age = 3 * laxmis age + 4

49 = 3m + 4

then m = 15

3. highest marks = 2 * lowest marks + 7

87 = 2m + 7

then m = 40

4. vertex angles = twice their base angle

base angle = b

vertex angle = 2b

2b + 2b + b = 180

5b = 180 , then b = 36 degrees

and 2b = 72 degrees
