Answer:
(5, 4)
Step-by-step explanation:
given the 2 equations
y = 3x - 11 → (1)
y = 4 → (2)
Substitute y = 4 into (1)
3x - 11 = 4 ( add 11 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5
solution is (x , y) = (5, 4)
Answer:
Look below
Step-by-step explanation:
Average means the middle of two numbers.
If the larger number is exactly one more or an odd number more than the smaller, it is possible for a half point to occur.
So find out Y first with the equation 2y+6=8y-102 which is y=18
Then plug in y for 8y-102 which is 42
Finally make the equation 3x+42=180 to find x which is 46
5-5+25/5
5-5+5
0+5
5
The answer is 5.
