00:00:00.960 --> 00:00:10.530
Use the shown graph to solve the given simultaneous equations: two π₯ minus three π¦ equals six, seven π₯ plus three π¦ equals 21.
00:00:12.910 --> 00:00:23.750
To solve these two equations, what weβre looking for is the point that these two lines intersect; the place where their π₯- and π¦-values are the same.
00:00:25.390 --> 00:00:28.160
This is the point on the graph where these lines intersect.
00:00:30.300 --> 00:00:36.050
If you look closely, youβll see that these lines intersect at the point three, zero.
00:00:37.750 --> 00:00:42.170
The π₯-value for their intersection is three and the π¦-value is zero.
