Question

x-2y=0 and 3x+4y-20=0 solve by graphically.​

Answer 1

Step-by-step explanation:

To solve linear equations with two variables, we will first write them in standard form.

Let, x - 2y = 0 ---(1)

3x + 4y = 20 ---(2)

By multiplying equation (1) with 2, we get

⇒ 2x - 4y = 0 ---(3)

On adding equations (2) and (3), we will get,

Solving linear equations in two variables.

⇒ x = 20/5

⇒ x = 4

By substituting the value of x = 4 in equation (1), we get

⇒ 4 - 2y = 0

⇒ 2y = 4

⇒ y = 2

Thus, the value of x is 4, and the value of y is 2.
