Question

Solve 3x-2y=-1,5x-3y=2 by substitute method.

Answer 1

Answer:

x=1

y=1

Step-by-step explanation:

5x-3y=2 ------------------(1)

x=(2+3y)/5------------------(2)

3x-2y=-1 ------------------(3)

x in (3)

3[(2+3y)/5] - 2y = -1

(6+9y)/15 - 2y = -1

taking L.C.M

6+9y-30y=-15

-21y=-21

y = 1

next y in (2)

x = (2+3*1)/5

 = 5/5

= 1
