please help me ​

Answer 1

Answer:

(i) 7 + x = 21

(ii) 3X + 1 = 10

(iii) 7x - y = 32

Step-by-step explanation:

(i) Let the number be x

So, equation becomes 7 + x = 21

(ii) Three times of number X = 3X

Equation becomes = 3X + 1 = 10

(iii) Let the number which is to be subtracted from 7x is y

Equation becomes = 7x - y = 32
