System of Equations Word Problems Day 1

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the set of values that satisfy all equations in the system.

Front

How do you represent a word problem as a system of equations?

Back

Identify the variables, translate the relationships and conditions into equations, and ensure the equations reflect the problem's constraints.

Front

What does it mean to solve a system of equations?

Back

To solve a system of equations means to find the values of the variables that make all equations true simultaneously.

Front

What is the substitution method in solving systems of equations?

Back

The substitution method involves solving one equation for one variable and then substituting that expression into the other equation.

Front

What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the remaining variable.

Front

What is a linear equation?

Back

A linear equation is an equation that forms a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the meaning of 'x' and 'y' in a system of equations?

Back

In a system of equations, 'x' and 'y' typically represent the unknown variables that we are trying to solve for.

Front

How can you check if your solution to a system of equations is correct?

Back

You can check your solution by substituting the values back into the original equations to see if they hold true.

Front

What is a word problem?

Back

A word problem is a mathematical problem that is presented in a narrative form, requiring interpretation and translation into mathematical expressions.

Front

What is the significance of coefficients in a system of equations?

Back

Coefficients are the numerical factors in front of variables in equations. They determine the weight or influence of each variable in the equation.
