Question

please solve question no. 5 question if anyone give wrong then I will report you ​

Answer 1

Step-by-step explanation:

D=4

Dx=5

4×x=5

×=5/4

DY=16

4y=16

y=16/4

y=4

Answer 2

Part 5:-

★Given:-

99m + 101n = 88

101m + 99n = 122

★To Find:-

Value of m+n

★Solution:-

Adding the equations will give,

101m + 99n =122

+(99m + 101n = 88)

_____________________

200m + 200n = 210

m + n = 210/200 = 21/20

m + n = 21/20

$\boxed{ \sf m+n = \dfrac{21}{20}}$

Part 4:-

Given:-

D = 4

Dx= 5

Dy = 16

To find:-

Value of x and y

Solution:-

Dx = 5

4x = 5

x = $\sf \dfrac{5}{4}$

Dy = 16

4y = 16

y = $\sf \dfrac{16}{4} = 4$

y=4

Hope it helps
