Algebra Examples

$d - 2 e = - 2$ $3 d + 2 e = 26$

Step 1

To solve a system of $1$ variables, only $1$ equations are required. Choose the first two equations containing the variables in the system.

$d - 2 e = - 2$

Step 2

The addition method can only be used on systems of two equations, and both must contain a variable.

Can't be solved with addition method.
