Answer:
(x, y) = (-10/7, 92/7)
Step-by-step explanation:
12x + y = -4
y = 2x +16.
Substituting the value of y ( second equation ) into the first equation, we get:
12x + (2x + 16) = -4
14x + 16 = -4
14x = -20
x = -20/14 = -10/7.
Now, to find y, all we have to do is to substitute the value of x into the second eqation. We get:
y = 2 * (-10/7) + 16
y = -20/7 + 16
y = 92/7
