Question

How would you Solve each of these systems using the substitution method.
2x + 3y = -4
x − 2y = 5

mathstudent55 · Answer

The substitution method works like this for a system of 2 equations:
1. Solve one equation for one variable.
2. Substitute that variable in the other equation.
3. Now you have one equation in one unknown, so solve for that variable.
4. Substitute the variable you know into one of the original equations and get the other variable.

In this case, look at the second equation. It looks like solving the second equation for x is simple, so start with that.
