The cut out words say "Solve the system of equations..." I need an answer for what to put in the empty boxes, including the boxes with the number 0 in them. I have finished all of previous work but nobody is able to help me with this. Please help with an answer :)
​

When rates are expressed as a quantity of 1, such as 2 feet per second or 5 miles per hour, they are called unit rates. if you have a multiple-unit rate such as 120 students for every 3 buses, and want to find the single-unit rate, write a ratio equal to the multiple-unit rate with 1 as the second term.

What is the last question i don’t see it?
