Question

3x+2y=13,4x+y=14 by substitution method

Answer 1

Step-by-step explanation:

3x +2y=13

4x+y=14

y=14-4x

put the value of y in eq1.

3x+2(14-4x)=13

-5x+28=13

-5x=-15

x=3

Answer 2

Answer:

3x+2y=13 --equation 1

  4x+y=14 --equation 2

from equation 1 x = (13-2y)/3 --- equation 3

substituting equation 3 in equation 2

(4(13-2y)/3)+y=14

(52-8y)/3+y=14

52-8y = (14-y)*3

52-8y = 42-3y

52-8y+3y=42

52-5y=42

-5y=42-52

-5y=-10

5y = 10

y = 10/5

y = 2

putting  value of y in equation 2

4x + 2 = 14

4x = 14-2

4x = 12

x = 12/4=3

y = 2

x = 3
