Solve : xy/x+y =2/3 and xy/y-x=2 |
|
Answer» ong>Answer: xy/X+y=2/3
3xy=2(x+y)
3xy=2X+2y
3x=2x+2y/y
3x=2x/y+2
3x-2x/y=2
3xy-2x/y-2=0
3xy-2x-2y=0
3xy-2y=2x
x(3y-2y)=2x
y=2
In the second CASE
xy/y-x=2
2x/2-x=2
2x=2(2-x)
2x=4-2x
4x=4
x=1
THEREFORE, x=1 and y=2 |

Answer» ong>Answer: The VALUES of x and y in the given equation by substitution method is x=20 and y=30 for x\neq 0x =0 and y\neq 0y =0 Step-by-step explanation: Given equations are \frac{4}{x}+\frac{9}{y}=\frac{1}{2}\hfill (1) x 4
+ y 9
= 2 1
\hfill(1) and \frac{12}{x}+\frac{12}{y}=1\hfill (2) x 12
+ y 12
=1\hfill(2) for x\neq 0x =0 and y\neq 0y =0 Now solving the given equations by substitution method : Let a=\frac{1}{x}a= x 1
and b=\frac{1}{y}b= y 1
for x\neq 0x =0 and y\neq 0y =0 Equation (1) implies 4a+9b=\frac{1}{2}\hfill (3)4a+9b= 2 1
\hfill(3) Equation (2) implies 12a+12b=1\hfill (4)12a+12b=1\hfill(4) From equation (3) 4a+9b=\frac{1}{2}4a+9b= 2 1
4a=\frac{1}{2}-9b4a= 2 1
−9b a=\frac{\frac{1}{2}-9b}{4}a= 4 2 1
−9b
a=\frac{1}{8}-\frac{9b}{4}a= 8 1
− 4 9b
Now substitute the value of "a" in equation (4) 12(\frac{1}{8}-\frac{9b}{4})+12b=112( 8 1
− 4 9b
)+12b=1 \frac{12}{8}-\frac{108b}{4}+12b=1 8 12
− 4 108b
+12b=1 \frac{3}{2}-27b+12b=1 2 3
−27b+12b=1 -15b=1-\frac{3}{2}−15b=1− 2 3
-15b=\frac{2-3}{2}−15b= 2 2−3
-15b=-\frac{1}{2}−15b=− 2 1
b=\frac{1}{2\times 15}b= 2×15 1
b=\frac{1}{30}b= 30 1
Since b=\frac{1}{y}b= y 1
for y\neq 0y =0 b=\frac{1}{30}=\frac{1}{y}b= 30 1
= y 1
for y\neq 0y =0 Therefore y=30 Substitute the value of b in equation a=\frac{1}{8}-\frac{9b}{4}a= 8 1
− 4 9b
we get a=\frac{1}{8}-\frac{9(\frac{1}{30})}{4}a= 8 1
− 4 9( 30 1
)
=\frac{1}{8}-\frac{\frac{9}{30}}{4}= 8 1
− 4 30 9
=\frac{1}{8}-\frac{9}{120}= 8 1
− 120 9
=\frac{1}{8}-\frac{3}{40}= 8 1
− 40 3
=\frac{5-3}{40}= 40 5−3
=\frac{2}{40}= 40 2
a=\frac{1}{20}a= 20 1
Since a=\frac{1}{x}a= x 1
for x\neq 0x =0 a=\frac{1}{20}=\frac{1}{x}a= 20 1
= x 1
for x\neq 0x =0 Therefore x=20 Therefore x=20 and y=30 |

|
Answer» ong>ANSWER: PERIMETER of a SQUARE shaped floor is = 80m → 4a=80 → a=20m Thus, Length (a) = 20 m Breadth (a) = 20 m Height (h)= 9.5 m COST : Area of four walls and top 2(l+b)h+a² or 2(a+a)h+a² → 2(20+20)9.5+20² → 2(40)9.5+400 → 80 x 9.5 +400 → 760+400 → 1160m² Cost of painting 1 m² = Rs. 14 Therefore, Cost of painting 1160m² = Rs. {1160×14} = Rs. 16240 VOLUME : Volume of room = l x b x h or a x a x h = 20 x 20 x 9.5 = 380m³ Hence, Cost of Painting = Rs. 16240 Volume of room = 380m³ |
