WebMar 14, 2024 · Two linear equations in two variables which are satisfied by the same pair of values of the variables are called simultaneous linear equations in two variables. For example, 2x – y = 7 and 3x – 2y = 9. The values of x and y which satisfy both the equations are called the solutions of the simultaneous linear equations. WebApr 24, 2024 · Start by adding 72 to both sides of the equation to give you 14x = 70. Divide both sides by 14 to give you x = 5. Take this value for x and put it into one of the original equations. This would give you 4 * 5 + y = 24 if you use the second equation. Solve for y. In this example, 20 + y = 24. Subtract 20 from both sides to give you y = 4. WebAn equations of the form Ax + By + C = 0 is called a linear equation in two variables x and y where A, B, C are real numbers. Two linear equations in the same two variables are called a pair of linear equations in two variables.
