Answer 1

Answer:

Question:

Find the number if 18 is taken away from the 6 times of a number is 30.

Solution:

Let ‘a ‘ be the number.

Given: 18 is taken away from the 6 times of a number is 30.

6a – 18 = 30

6a = 30 + 18

6a = 48

a=48 / 6

a=8

Therefore, the number is 8.

Question 2:

Solve the equation given below and find the value of x and y

x + y = 3

x – y = 1

Solution:

Given,

x + y = 3 …(1)

x – y = 1 …..(2)

By solving two equations, we get

2x = 4

X = 4/2

x= 2

Substitute x= 2 in equation (1), we get

2 + y =3

y = 3 – 2

y = 1

Therefore, x = 2 and y =1
