The weight of the Yi ting’s older brother is .
Further explanation:
Given:
The weight of the Yi ting is 8.3kg and weight of her older brother is 4 times more than her weight.
Calculation:
Consider the weight of the Yi ting as and weight of Yi ting’s older brother as .
Since, the weight of the Yi ting’s older brother is 4 times more than the weight of Yi ting , it can be written as follows:
…… (1)
Now, substitute 8.3 for x in equation (1).
Thus, the weight of the Yi ting’s older brother is .
