Question

solve in the substitution
method 3x by 2- 5y by 3=-2
x by 3 + y by 2= 13 by 6​

Answer 1

Answer:

3x

−

3

5y

=−2

3

x

+

2

y

=

6

13

Now from eq2 will get

2x+3y=13

Now using substitution method

y=

3

13−2x

Now substituting y in eq 1 will get

⇒9x−

3

10(13−2x)

=−12

⇒27x−130+20x=−36

⇒47x=−36+130

⇒47x=94

⇒x=2

Now substituting x in eq 2 will get

⇒2×2+3y=13

⇒4+3y=13

⇒3y=13−4

⇒3y=9

⇒y=3

⇒x=2,y=3
