The given equations are:
y = 9 - 3x and x = 8 - 2y
The given equations are simultaneous equations and hence can be solved in this manner.
3x = 9 - y ---------------(1)
x = 8 - 2y ---------------(2)
Multiply eqn (1) by 2 and subtract if from eqn (2)
thus we get:
6x = 18 - 2y
x = 8 - 2y
==============
5x = 10
==> x = 10/5
==> x = 2
By back substitution, we get: y = 9 - 3x
y = 9 - 6
y = 3
Hence, the solution.
