This kind of hard to explain without an example, so I'll do my best...
All you have to do is isolate a variable on one side of the equals sign without a coefficient. Ex: x=2y+3 The x is all alone and ready to go into the second equation.
Substitute into the second equation. Ex: 2x+5=3 Substitute: 2(2y+3)+5=3
I hope this helps!
In this item, we are to divide one (1) inch into 16 equal parts to be able to conclude that American standard system is less accurate than the metric system.
16 parts of 1 inch = 1 inch / 16 = 0.0625 inch
This in itself is already a proof enough that there are 4 decimal places after the decimal point which makes this hard to properly measure.
Whereas, if we are to divide a centimeter into the millimeters, we will have 10 equal parts and that would be 1 mm = 0.1 cm.
The number above only has one decimal place and the level of accuracy should be higher.
