Question

the value of x satisfying both the equations 4x-5=y and 2x-y=3 when y=-1 is......?​

Answer 1

Answer:

The answer to your question is....

Answer 2

The value of x satisfying both the equations is x = 1, as well as the value of 'x' when y=-1 for both the equations is x=1.

Given:

The equations 4x-5=y and 2x-y=3.

The value of y=-1.

To Find:

The value of 'x' that satisfies both the equations.

The value of the 'x' when y = -1.

Solution:

We have been given two equations:

4x - 5 = y

⇒ 4x - y = 5 ......................(I)

2x - y = 3    ......................(II)

To find the value of 'x' that satisfies both the given equations, we need to solve them simultaneously.

Subtracting equation (II) from (I), we get:

(4x - y)-(2x - y) = 5-3

⇒2x = 2

⇒ x = 1.

Hence, the value of 'x' that satisfies both the equations is x=1.

Now, when y = -1

a) Equation (I) becomes,

4x - (-1) = 5

⇒ 4x + 1 = 5

⇒ 4x = 4

⇒ x = 1.

b) Equation (II) becomes,

2x - y = 3

2x - (-1) = 3

⇒ 2x = 2

⇒ x = 1.

∴ The value of x satisfying both the equations is x = 1, as well as the value of 'x' when y=-1 for both the equations is x=1.
