Question

12x+y=−4 y=2x+16 im really confused on how to do this, i need to find the solution

Answer 1

(x, y) = (-10/7, 92/7)

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
