boxes on one side of the equation to make this
- 01:08
problem easier to solve We could do whatever we want
- 01:10
Toe one side of the equation as long as we
- 01:12
also do it to the other side So let's subtract
- 01:16
a b from both sides Now we have the equation
- 01:18
Five equals b plus one next week and subtract one
- 01:22
for meat side and we get four equals to be
- 01:26
all we have to do at this point it's by
