The sum of two numbers is -4 and their difference is -10. find the numbers. (translate to a system of equations and solve)

-4

step-by-step explanation:

(-4+8)=-(4-8)=-8+4=-4

step-by-step explanation:

i got the answer right on edg.

congruent: (geometry) (of figures) identical in form; coinciding exactly when superimposed.

the answer to this in exact form is 4/35 but in decimal form its 0.1142857

hope this if needed hmu

x=-2

step-by-step explanation:

i began by flipping the problem to give me x= on the left (keeps it clearer for me).   so my problem simply became 10x-3=4x-6.  

1)   subtract 4x from the right side, which equals 0.   you do the same to the left of the equal as the right; therefore, subtract 4x from 10x, leaving 6x on the left.

              10x-3=4x-6   :   4x-4x on the right leaves only the -6        

2)             6x-3= 0-6 :    

                6x+3=   -6

3) divide
