Answer:
the answer is 90
Step-by-step explanation:
x + y = 12
Equation 2: Difference:
x - y = 4
Solution:
x + y = 12
x - y = 4
-------------
Add the two equations together:
2x = 16
Divide both sides by 2:
x = 8
Solve for y:
Use equation 1 substituting for x:
x + y = 12
8 + y = 12
Subtract 8 from both sides:
y = 4
Answer:
one number is 8 and the other number is 4.
8 + 4 = 12
8 - 4 = 4

okay so i assume you meant these two:
y=-382 and y=6x+3
Answer:
y=-382
x=-385/6
Step By Step:
y=−382;y=6x+3
Step: Solve y=−382 for y:
y=−382
Step: Substitute −382 for y in y=6x+3:
y=6x+3
−382=6x+3
−382+−6x=6x+3+−6x (Add -6x to both sides)
−6x−382=3
−6x−382+382=3+382 (Add 382 to both sides)
−6x=385
Divide both sides by -6.
x=-385/6
y=-382
