write two solutions for each of the following question: a) 5x-2y=7 (b) x=6y
Answers
Step-by-step explanation:
We are given,
3x + 4y = 7
Substituting x = 1
In the given equation, We get
3 ×1 + 4y = 7
4y = 7- 3 - 4 = 4Y
Y = 1
Thus x = 1 and y = 1 is the solution of 3x + 4y = 7
Substituting x = 2 in the given equation, we get
3× 2 + 4y = 7
4y = 7 - 6
y = 1/4
Thus x = 2 and y = 1/4 is the solution of 3x + 4y = 7
(ii) We are given, x = 6y
Substituting x = 0 in the given equation, we get 0 = 6y
6 y = 0
y = 0
Thus x = 0, ⟹ Solution (0, 0)
Substituting x = 6
6 = 6y
y = 6/6
y = 1
⟹ Solution (6, 1)
Answer:
