Answer 1

Method:

2.Substitution

Step-by-step explanation:

6.One equation is in standard form and one is solved for variable already

The first equation is in standard form and the second equation is solved for y already. Then, to solve the system, you have to substitute the value of y in the second equation into the first equation.
