Answer:
(-8,-10)
Explanation:
we have the two equations x-2y=12 and y=3x+14.
I'm going to assume this is a system of equations and we are looking for the solution.
we can use the substitution method as y is "defined".
x-2y= 12
substitute y = 3x + 14
x-2(3x+14)=12
distribute
x - 6x -28 = 12
combine like terms
-5x - 28 = 12
add 28 to both sides
-5x = 40
divide both sides by -5
x = -8
Now we plug in the value of x into one of the equations and solve for y
y = 3x + 14
x = -8
y = 3(-8) + 14
y = -24 + 14
y = 10
the solution is (-8,-10)
