Questions & Answers

Q: What are simultaneous equations?

Simultaneous equations are a set of equations with multiple variables that can be solved simultaneously to find the values of those variables. In this case, we are dealing with equations containing x's and y's.

Q: What is the first step in solving simultaneous equations?

The first step is to make the coefficients of one variable the same in both equations by manipulating the equations through multiplication or division to simplify the process of elimination.

Q: How do we find the value of x in simultaneous equations?

By making the coefficients of y the same in both equations, we can add or subtract the equations to eliminate one variable, leaving us with an equation to solve for the value of x.

Q: Why do we substitute the value of x back into the equations?

Substituting the value of x back into the equations helps us find the value of the other variable, y, by simplifying the equation and solving for the remaining unknown variable.

Summary & Key Takeaways

• Simultaneous equations involve using two algebraic equations with x's and y's to solve unknown variables.

• To solve, make coefficients the same by multiplying one equation and adding them together.

• Substituting the found value of x back into the equations helps determine the value of y.
