How to fill out systems by substitution
How to fill out systems by substitution:
01
Identify the systems: Start by identifying the two equations that form the system. Make sure they are written in standard form, with the variables on the left side and the constants on the right side.
02
Solve one equation for one variable: Choose one of the equations and solve it for one variable in terms of the other variable. This will help us substitute it into the other equation later.
03
Substitute the expression: Take the expression you found in step 2 and substitute it into the other equation. This will create an equation with only one variable.
04
Solve the equation: Solve the resulting equation for the remaining variable. This will give you a value for that variable.
05
Substitute the value back: Take the value you found in step 4 and substitute it back into either of the original equations. This will help you find the value of the other variable.
06
Check the solution: Plug the values you found for the variables back into both of the original equations to verify that they satisfy both equations. If they do, then you have found the solution to the system.
