Two numbers have a sum of 19 and a difference of 5. find the two numbers

Let "x" represent the first number and "y" represent the second number.

Set up a system of equations, solve one of the variables using any method (I will be using the elimination method), and then plug that solution into either equation to solve for the remaining variable.

x + y = 19

+ x - y = 5

2x = 24 added the equations to eliminate "y"

x = 12 divided both sides by 2

12 + y = 19 substituted "x = 12" into the first equation

y = 7 subtracted 12 from both sides

12 and 7

the fist one is not equalvalent but i think th second one isand the third isnt definetly or the last one is i think. hope this !

step-by-step explanation:

i believe the answer is d.

hope it you! : d
