Step-by-step explanation:

ACCORDING TO THE WORD PROBLEM THE EQUATION WILL BE

7X+50+40=300

7x+90=300

7x=300-90

7x=     210

x=210/7x

x=30

Answer 2

Let the number be n.

According to the question,  

7n + 50 + 40 = 300

⇒7n + 90 = 300

⇒7n = 300 − 90

⇒7n = 210

⇒ n = 7/210

⇒ n = 30

Thus, the required number is 30.
