Answer:
Small box weighs 13.75 kg & large box weighs 15.75 kg
Step-by-step explanation:
We can write 2 simultaneous equation and solve for weight of each box.
<em>Let weight of large box be l and small box be s.</em>
<em />
"<u>3 large boxes and 5 small boxes has a total weight of 116 kilograms</u>":
and
"<u>9 large boxes and 7 small boxes has a total weight of 238 kilograms</u>":
<em>Now we can solve for l in the 1st equation and put it into 2nd equation and get s:</em>
<em></em>
<em>now,</em>
<em></em>
<em />
<em>now we plug in 13.75 into s into equation of l to find s:</em>
