There are two ways of solving this problem:
Method 1: substitution.
Make X (or Y) the subject of one equation: X= (4-6Y)/4
Substitute this into the other equation:...

From SOHCAHTOA we choose CAH based on trianglecos(theta)= adjacent / hypcos(72)=x / 3.4
3.4cos(72)=xOn calculator find x=1.0506... =1.05 (2dp)

Carbon Dioxide molecules consist of 2 oxygen and 1 carbon atom. The oxygen atoms are bonded to the carbon atom using double covalent bonds.

Simultaneous equations are used to help us find unknown values. An example of simultaneous equations is:1) x + y = 62) 2x + 3y = 16We don't know what the value or X or Y is but we know that together they ...
