Y = -x + 4
y = 3x + 3
3x + 3 = -x + 4
3x + x = 4 - 3
4x = 1
x = 1/4
y = 3x + 3
y = 3(1/4) + 3
y = 3/4 + 3
y = 3/4 + 12/4
y = 15/4
solution is (1/4,15/4)
so line y = -x + 4 intersects the line y = 3x + 3 at (1/4,15/4)

Answer:
The numbers are 5 and 8.
Step-by-step explanation:
We know:
m
-n=3
And we know:
m
+n=13
Next, solve the first equation for m:
m-n+n=3+n
m-0=3+n
m=3+n
Then, substitute 3+n in the second equation and solve for n:
m+n=13 becomes:
(3+n)+n=13
-3+3+2n=-3+13
0+2n=10
2n=10
n=5
Now, substitute 5 for in the solution to the first equation and calculate m:
m=3+n becomes:
m=3+5
m=8
The solution is n=5 and m=8
Answer:
Step-by-step explanation:
hello :
10x - 29 - 7x=-53
add 29 : 10x-7x= -53+29
3x=-24
x= -24/3 = -8
