Question

=
x = 1 - 3
r = -2
(x, y) = (-2, 3) is the solution.
Practice Set 1.1
1) Complete the following activity to solve the simultaneous equations
5x + 3y = 9 -----(I)
Place x = 3 in equation (1).
5x + 3y = 9
2x – 3y = 12
Let's add eqations (1) and (II).
5x + 3y = 9
3y = 9 -
+
3y =
2x - 3y = 12
1
X =
Y =
