SOLVE THE FOLLOWING LINEAR EQUATION BY THE SUBSTITUTION METHOD 3/2x -5/3y=-2; x/3+y/2=13/6

Open in App

Solution

= -2 …………………..(1)
= …………………..(2)
Taking eqn (1)
= -2
,
9x-10y = -12 …………………….(3)
9x = -12 +10y
x = …………………(4)
Taking eqn (2)
=
=
2x+3y = 13 ……………………..(5)
Substitute the value of x in (5)
2* +3y = 13
+3y = 13
= 13
-24 + 47y = 117
47y = 117+24
47y = 141
Y = = 3
Put the value of y in (4)
x =
=
= 18/9
= 2
