solve the following equation 2y+4 by y+4=1
Answers
Answer:
Given: Linear Equation x - 2y = 4
We can substitute the values in the given equation and can check whether LHS is equal to RHS or not.
if LHS = RHS then it is a solution for the given equation.
x - 2y = 4 --- Equation (1)
i) Consider (0, 2)
By Substituting x = 0 and y = 2 in the given Equation (1)
x - 2y = 4
0 - 2(2) = 4
0 - 4 = 4
- 4 ≠ 4
L.H .S ≠ R.H .S
Therefore, (0, 2) is not a solution to this equation.
ii) Consider (2, 0)
By Substituting, x = 2 and y = 0 in the given Equation (1),
x - 2y = 4
2 - 2(0) = 4
2 - 0 = 4
2 ≠ 4
L.H .S ≠ R.H .S
Therefore, (2, 0) is not a solution to this equation.
iii) (4, 0)
By Substituting, x = 4 and y = 0 in the given Equation (1)
x - 2y = 4
4 - 2(0) = 4
4 - 0 = 4
4 = 4
L.H .S = R.H .S
Therefore, (4, 0) is a solution to this equation.
iv) (√2, 4√2)
By Substituting, x = √2 and y = 4√2 in the given Equation (1)
x - 2y = 4
√2 - 8√2 = 4
-7√2 ≠ 4
L.H .S ≠ R.H .S
Therefore, (√2, 4√2) is not a solution to this equation.
v) (1, 1)
By Substituting, x = 1 and y = 1 in the given Equation (1)
x - 2y = 4
1- 2 (1) = 4
1 - 2 = 4
-1 ≠ 4
L.H .S ≠ R.H .S
Therefore, (1, 1) is not a solution to this equation.
