\[x - 2y = -3\]
Now that we have the value of y, substitute it back into one of the original equations to find x. We’ll use equation (2):
\[7y = 19\]
\[x = rac{-21 + 38}{7}\]
\[y = rac{19}{7}\]
Ejercicio 180 presents a system of linear equations with two variables, x and y. The goal is to find the values of x and y that satisfy both equations simultaneously. The exercise is as follows:
\[x - rac{38}{7} = -3\]
