When using substitution to solve a system of equations , how can you tell when a system has no solution

If you have a false statement at the end.

Step-by-step explanation:

When using substitution to solve a system of equations, you can tell when the system has no solution if the equation at the end produces a false statement.

For example, at the end if you have something like 3x + 1 = 3x - 4. You would subtract 3x from both sides of the equation and be left with 1 = -4.

This is a false statement, 1 does NOT equal -4. Therefore, system of equations has no solution.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
