# The Graph of The Following System of Equations is −2x + y = 3 and 4x + 2y = 2. Solve this using the graph.

An equation of degree 1 is called linear equations. The standard form of linear equations in two variables is ax + by = c, where a, b and c are constants.

## Answer: The solution for the system of linear equations -2x + y = 3 and 4x + 2y = 2 is (x, y) = (-0.5, 2)

Let's solve the system of linear equations in two variables.

**Explanation:**

The given equations are -2x + y = 3 --- (1) and 4x + 2y = 2 --- (2)

From the graph, it is clear that the intersecting point of the given two linear equations is (-0.5, 2). So, this is the solution of the given system of equations.

Let's solve the equations algebraically.

From equation (2), we get

4x + 2y = 2

x = (2 - 2y) / 4

To solve the system of linear equations, we will substitute value of x = (2 - 2y) / 4 in equation (1) and solve for x.

⇒ -2((2 - 2y) / 4) + y = 3

⇒ -4 + 4y + 4y = 12

⇒ 8y = 12 + 4

⇒ 8y = 16

⇒ y = 2

Put y = 1 in equation (2).

⇒ x = (2 - 2(2))/4 = (2 - 4)/4 = -2/4

⇒ x = -0.5
