Question

1.Evaluate the simultaneous equations 2x + 4y = 13; x + y = 4 by using the Elimination
Method.

Answer 1

Answer:

x=3/2 , y= 5/2

Step-by-step explanation:

x + y= 4

x =4 - y

2x + 4y = 13

2 (4 - y) + 4y =13

8 - 2y + 4y =13

8 + 2y = 13

2y = 13 - 8

2y = 5

y=5/2

x= 4 - 5/2

x= 8 - 5/2

x= 3/2
