Question

Solve the following pair of simultaneous equation using the elimination method. 3x – y = 14.2x + y = 26.

Answer 1

Answer:

x = -12

Step-by-step explanation:

Given equation (i) = 3x - y = 14

equation (ii) = 2x + y = 26

Subtracting equation (ii) from (i), we get

3x - y = 14

- 2x + y = 26

=>(3x - 2x) = (14 - 26)

(y gets cancelled out)

= x = -12
