Good work! You've been able to reduce the system of equations from 3 equations and 3 unknowns to 2 equations with 2 unknowns. What can you do to combine those last two equations to eliminate the "b" terms?kaydis said:

A linear equation is an algebraic equation that contains only terms with a degree of 1. It can be written in the form of y = mx + b, where m is the slope and b is the y-intercept.
In order to solve a system of linear equations with 3 unknowns and 3 equations, you can use the substitution method or the elimination method. Both methods involve isolating one variable in one equation and substituting it into the other equations until all 3 unknowns have been solved for.
Yes, there can be more than one solution to a system of linear equations with 3 unknowns. This is known as an infinite number of solutions. This can happen when all three equations are essentially the same, resulting in multiple possible solutions.
Yes, it is possible for a system of linear equations with 3 unknowns to have no solutions. This can happen when the equations are contradictory, meaning they have no common solution that satisfies all three equations. This is known as an inconsistent system.
Yes, a system of linear equations with 3 unknowns can be solved graphically by graphing each equation on the same coordinate plane and finding the point of intersection. However, this method can be less precise and time-consuming compared to the substitution or elimination method.
