## Algebra 1: Common Core (15th Edition)

The first step in solving the system is finding that $y=2-1.2x$ (explained in detail below).
The first step is to select one of the equations, which we solve for one of the variables. To avoid fractions in this first step, we search for a variable with a coefficient 1 or -1. In this case, the variable y in the first equation would be our choice, as its coefficient is $1.$ So, the first step in solving the system is finding that $y=2-1.2x$ In the next step, $y$ would be substituted with $2-1.2x$
