Question

x-2y=13 and 2x-3y=14 substitute method​

Answer 1

Answer:

x-2y=13

x = 13 +2y (i)

Substituting (i) in 2x-3y=14

2x-3y=14

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

26 +4y -3y =14

26 +y = 14

y = -12

Substituting y = -12 in (i),

x = 13 - 2(-12)

= 13 +24

x = 37

Answer 2

Step-by-step explanation:

By substitution method

x=13+2y. ( 3)

put value of x in eq 2

2(13+2y)= 13+2y

26+4y=13+2y

2y=-

y= 13/2

x=13+2*13/2
