The sum of two numbers is 38. Their difference is 50. What are the numbers?<br><br> 20 POINTS

enot [183]

Let, the numbers = x,y
Now, x + y = 38
x - y = 50, x = 50 + y

Substitute it into first equation,
50 + y + y = 38
2y = 38 - 50
y = -12 / 2
y = -6

Substitute it into first equation,
x - 6 = 38
x = 38 + 6 = 44

So, your final answer is x = 44 & y = -6

Hope this helps!

Answer:

Step-by-step explanation:

$y=4x-4\\\\\text{Substitute the coordinates of each points to the equation}\\\text{and check the equality.}\\\\1.\ (0,\ 4)\to x=0,\ y=4\\\\4=4(0)-4\\4=0-4\\4=-4\qquad\bold{FALSE}\\\\2.\ (0,\ -4)\to x=0,\ y=-4\\\\-4=4(0)-4\\-4=0-4\\-4=-4\qquad\bold{TRUE}\\\\3.\ (-4,\ 0)\to x=-4,\ y=0\\\\0=4(-4)-4\\0=-16-4\\0=-20\qquad\bold{FALSE}\\\\4.\ (4,\ 0)\to x=4,\ y=0\\\\0=4(4)-4\\0=16-4\\0=12\qquad\bold{FALSE}$
