Cancel out one kind of variable from that side and put it on the other side.

Examples:

5x + 5y = 15
---- - 5y ------- - 5y

5x = 15 - 5y

6c - 2b = 48
---- +2b -------- + 2b

6c = 48 + 2b

Hope this helps!

An employee shreds 341 pages in 11 minutes of work. How many pages will she shred in 20 minutes?
gavmur [86]

We have been given that an employee shreds 341 pages in 11 minutes of work.

First of all we will divide 341 by 11 to find number of pages shred by employee in one minute.

\text{Pages shred by employee in one minute}=\frac{341}{11}=31

Now let us multiply 31 by 20 to find number of pages shred by employee in 20 minutes.

\text{Pages shred by employee in 20 minutes}=31\cdot20=620

Therefore, employee will shred 620 pages in 20 minutes.
