Step-by-step explanation:
The given system of equation
is
- 5 + = 5 ..()
3
- = 6.(i)
From (i), we get
3x+7y 21 = 5
» 3x + 7x = 105
→ 3x
=
1.5 – 7y
105-7y 3
From (ii), we get
9x-2y
18
=
69x - 2y = 108... (iii)'
=
Substituting x = we get
105-7y 3
9 105-7у 3 - 2u = 108
948-63y 2y = 108
3
=> 945 - 63y - y = 108 x 3
=> 945 - 69y = 324
945 – 324 69y =
=> 69y = 621 =
=> y = 621/69 = 9
Putting y = 9in x = get
Concep
in (ii)=> y = 621/69 = 9
Putting y = 9in x
get
X =
17966

Hence, the solution of thee given system of equations is x = 14, y = 9
