X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Answer:
Its either L or N im not sure but if i had to guess out of the two i think its L.
Step-by-step explanation:
546 divide by 6 = 91 so 91 times 6 = 546
All real numbers since there is no exclusions. (-inf, inf)
It would be: -12 + 15x = 3(-4+5x)
So, after common factor out, your answer is 3(-4+5x)
Hope this helps!
