Question

write the following as equation.

Answer 1

(vii)

Let the number be x
so,

7x - 4 = 10

Further solving the equation,
We have ,

7x = 10 + 4

7x = 14
x = 14/7

x = 2


(viii)
Let the number be p (given)

2p + 3 = 17

Further , solving the equation,
We have

2p = 17 - 3

2p = 14
p = 14/2

p = 7

Answer 2

Answer:

4-7x=10

2x+3=17

Step-by-step explanation:

i) Let number be= x

A.T.Q. (According to question)

4-7x=10

ii) Let number be= x

A.T.Q. (According to question)

2x+3=17

SOLVING THE EQUATIONS:

i)  4-7x=10

   7x=10+4

    7x=14

    x=14/7

    x=2

ii)  2x+3=17

    2x=17-3

     2x=14

      x=14/2

      x=7
