Question

simultaneous linear equation

Answer 1

Consider two linear equations in two variables, x and y, such as: 2x - 3y = 4, 3x + y = 1. We have here two equations and two unknowns. In order to find a solution for this pair of equations, the unknown numbers x and y have to satisfy both equations. Hence, we call this system or pair of equations simultaneous equations. 

calculate simultaneous linear equation :

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.Step 2: Subtract the second equation from the first.

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.Step 2: Subtract the second equation from the first.Step 3: Solve this new equation for y.

Step 1: Multiply each equation by a suitable number so that the two equations have the same leading coefficient.Step 2: Subtract the second equation from the first.Step 3: Solve this new equation for y.Step 4: Substitute y = 2 into either Equation 1 or Equation 2 above and solve for x.
