Question

Solve the following system of equations by substitution
method:
x + y = 14
x - y = 2
​

Answer 1

Answer:

x = 8

y = 6

Step-by-step explanation:

x + y = 14 (1)

x - y = 2 (2)

from (1) we get,

x = 14 - y (3)

putting (3) in (2) we get,

(14 - y) - y = 2

14 - 2y = 2

14 - 2 = 2y

12 = 2y

.; y = 12/2 = 6.......(4)

putting (4) in (3), we get

x = 14 - 6

  = 8

therefore, x = 8 and y = 6
