Question

X/2+2y/3= -1 , x-y/3 = 3 solve that by subtitiuson method pls​

Answer 1

Solution

Given :-

• x/2 + 2y/3 = -1 _________(1)
• x - y/3 = 3 ____________(2)

Find :-

• Value of x & y.

Explanation

Substitution Method.

By, equ(2)

• x = 3 + y/3 __________(3)

Keep Value of x in equ(1)

==> (3 + y/3)/2 + 2y/3 = -1

==> (9+y)/6 + 2y/3 = -1

==> (9 + y) + 4y = -6

==> 5y = -6 - 9

==> 5y = - 15

==> y = -15/5

==> y = -3

Keep Value of y in equ(3)

==> x = 3 + (-3)/3

==> x = 3 - 3/3

==> x = 3 - 1

==> x = 2

Hence

• Value of x = 2
• Value of y = -3
