15x+2x can be written as (15+2)x, since they have the same variable, so 15+2 can go inside the parentheses, and the <em>x</em> can go on the outside, meaning both 15 and 2 are multiplied by x.

<h3>Graph of system of linear equations </h3>

From the question, we are to graph the given system of equations.

The given system of equation is

y + 2x = −1

3y − x = 4

The graph of the given system of equations is shown below.

From the graph, we can observe that the solution to the given system of equation is given by two lines that intersect at the point (-1, 1).

Hence, the system of equations has one solution (-1, 1)
