Let the numbers be x&y
X+y=109
Taking a as the smallest number we multiply by 4
So according to the question you will have this equation
Y(as the largest number) -4x=4. Y-4x=4
Then find y
Y=4x+4
Substitute y on the first equation to get a
X+y=109
X+4x+4=109
X=21
21+y=109
Y=88

48-X or C-48 would be the answer
Is this rearranging of equation??
-n+sx=n-a
sx=2n-a
x=2n-a/s
Answer:
Width=6.5 cm
Length=12 cm
Step-by-step explanation:
Step 1: Express the lengths and widths
Width=w
Length=l, but 1 cm less than twice the width=(2×w)-1=2 w-1
Step 2: Solve for the length and width
A=L×W
where;
A=area of the photograph
L=length of the photograph
W=width of the photograph
In our case;
A=91 cm²
L=2 w-1
W=w
91=(2 w-1)w
2 w²-w=91
2 w²-w-91=0, is a quadratic equation
solve for w
w={-1±√(-1²-4×2×-91)}/(2×2)
w=(-1±27)/4
w=(27-1)/4=6.5, or (-1-27)/4=-8
Take w=6.5 cm
L=(2×6.5)-1=13-1=12 cm
Width=6.5 cm
Length=12 cm
