Answer:
domain: {x ≠ 0}
Step-by-step explanation:
Answer:
If you're supposed to use elimination to find (x, y) the answer is (6, 1)
Step-by-step explanation:
Add:
2x+3y=15
x-3y= 3
y cancels out and left with...
2x=15
x=3
that becomes
3x=18
find x
18/3= 6
x=6
Then plug in x (which is 6) to one of the equations to solve for y
6- 3y= 3
-3y= 3-6
-3y= -3
y= 1
(x, y) equals (6, 1)
Answer:
x= 1, y=3
Step-by-step explanation:
y= 2x +1
y= -x +4
Those two equation are in a system that means they need to be true in the same time. Just like I would say look for a car that is red and is a truck in this case we look for x and y is true that y = 2x+1 and is true that y= =x+4.
so y= 2x+1 but y is -x+4 so substitute
-x+4 = 2x +1, add x on both sides
4= 2x+x +1, subtract 1 from both sides
4-1 = 2x +x, combine like terms
3 = 3x , divide both sides by 3
x=1
if x=1 we substitute in y= -1 +4 = 3
