Example 2.
- 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.

Keeping this in consideration, what is simultaneous method?
There are many ways of solving simultaneous equations. This is a process which involves removing or eliminating one of the unknowns to leave a single equation which involves the other unknown. The method is best illustrated by example. Example Solve the simultaneous equations 3x + 2y = 36 (1) 5x + 4y = 64 (2) .
Beside above, how do you solve simultaneous equations graphically? Steps
- Write your 2 equations clearly. Write your 2 equations in an organised, clear way.
- In the first equation, let x be 0.
- Let y be 0.
- Draw a graph with 4 quadrants.
- In the second equation, let x be 0.
- Let y be 0.
- Draw the line of the second equation on the same graph as before.
- Look at the point in which the 2 lines meet.
People also ask, how many types of simultaneous equations are there?
We use three different methods to solve simultaneous equations. They are: Elimination method. Substitution method.
How do you solve system of equations?
Follow the steps to solve the problem.
- Step 1: Multiply the entire first equation by 2.
- Step 2: Rewrite the system of equations, replacing the first equation with the new equation.
- Step 3: Add the equations.
- Step 4: Solve for x.
- Step 5: Find the y-value by substituting in 3 for x in either equation.
Related Question Answers
What is the method of elimination?
In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.
How do you solve simultaneous quadratic equations?
The simultaneous solution of a linear equation and a quadratic equation is given by the point or points of intersection of the line and parabola representing the equations. To find the solution, eliminate y (or x) by substitution; and solve the quadratic equation thus formed in x (or y).
