Answer: 7
Step-by-step explanation:
Given: Eight times the result of subtracting 3 from a number is equal to the number increased by 25 what is the number.
Let x be the number.
According to the question, we have
8(x-3)=x+25
⇒8x-24=x+25 [open parenthesis]
⇒8x-24-x=25 [Subtract x from both sides
]
⇒7x-24=25
⇒7x=49 [Add 24 to both sides
]
⇒x=7 [divide both sides by 7
]
Therefore, the number is 7.
