1. To solve for s you need to get s alone on the left side.
2. subtract 4t from both sides of the equation.
s+4t=r
-4t -4t
3. Your answer is:
s=r-4t
Answer:

8x+3+4y-7-y
2) 4x3x-4x7
12x-4 x 7
3) 18x+12
6(3x+2)
4) 9x+ 1-7x +4+5x- 3
7x+1+4-3
Im sorry I wanted to answer it as quick as possible sorry if you dont understand.
Answer:
He had hiked 3/12 of a mile so the answer is 8/12 of a mile
Step-by-step explanation:
You need to make 1/4 into twelves by multiplying both sides by 3 to get 3/12.
You take that and subtract it from the total distance. 11/12 - 3/12 = 8/12
X+yz : is the answer to your question.
1. 5m+3n=41
3m-6n=9 (multiplying the first equation by 3 and the second by 5), we get;
15m+9n=123
15m-30n= 45 (subtracting the two equations)
39n = 78
n = 2, and
to get m we substitute n with 2
3m = 9+6(2)
3m = 21
m = 7
Therefore, n=2 and m=7
2. 6g +8h=40
-6g +2h = -20(Adding the two equations to eliminate g)
10 h= 20
h =2
to get g we substitute h with two
6g= 40- 8(2)
= 24
g= 4
Therefore, g =4 and h =2
3. 9x +5y =35
2x + 5y =0 (subtracting the two equations to eliminate y)
7x =35
x= 5
To get y we substitute x with 5
5y=35-9(5)
5y = -10
y = -2
Therefore, x=5 and y=-2
