Question:-
Find x , y , z and w if
Answer:-
Given:
On comparing both sides we get,
- x - y = - 1 -- equation (1)
- 2x - y = 0 -- equation (2)
- 2x + z = 5 -- equation (3)
- 3z + w = 13 -- equation (4)
Subtract equation (1) from (2).
→ 2x - y - (x - y) = 0 - ( - 1)
→ 2x - y - x + y = 1
→ x = 1
Substitute x value in equation (1).
→ 1 - y = - 1
→ 1 + 1 = y
→ 2 = y
Substitute x value in equation (3).
→ 2 * 1 + z = 5
→ z = 5 - 2
→ z = 3
Substitute z value in equation (4).
→ 3 * 3 + w = 13
→ w = 13 - 9
→ w = 4
Therefore,
- x = 1
- y = 2
- z = 3
- w = 4
