MAT1503 - ASSIGNMENT 03 SOLUTIONS (SEMESTER 01 -2022) 
(a)	(i) We shall do this by substitution. Thus 
2 (t + 2) + 4 (−2t − 1) + 6t 
= 2t + 4 − 8t − 4 + 6t 
= 0 
Also 
4 (t + 2) + 5 (−2t − 1) + 6t 
= 4t + 8 − 10t − 5 + 6t 
= 3 
and finally 
7 (t + 2) + 8 (−2t − 1) + 9t 
= 7t + 14 − 16t − 8 + 9t 
= 6 
Thus, x = t+2, y = −2−1, z = t satisfy all three equation. This solution is general since it has the parameter t, enabling the generation of any other solution from this...
