Question

Draw the graph of the equation 2x+3y-6=0 and determine from the graph whether x=3, y=0 is a solution or not. Also from the graph, find the value of x when y=4.​

Answer 1

Answer :-

• Please see the attachment for the solution.

Step-by-step explanation :-

Points to remember while making these questions

• Always try to find the value of x.
• Put different value in the y to get x.
• Try to use substitution method.
• Always make the table after substituting the values.

METHODS FOR SOLVING LINEAR EQUATION:

1. ELIMINATION METHOD :-

The elimination method is the process of removing the variable from the system of equations, whereas the substitution method is the process of replacing a variable with a value to find the solution for the system of equations.

2. SUBSTITUTION METHOD :

For instance, the system of two equations with two unknown values, the solution can be obtained by using the below steps. Here, the list of steps is provided to solve the linear equation. They are

• Simplify the given equation by expanding the parenthesis
• Solve one of the equations for either x or y
• Substitute the step 2 solution in the other equation
• Now solve the new equation obtained using elementary arithmetic operations
• Finally, solve the equation to find the value of the second variable
