Question

solving following simultaneous equation 4 x minus 5 y is equal to 17 and x minus 5 y is equal to 8 we get​

Answer 1

Answer:

4x-5y=17

x-5y=08

3x=9

x=9÷3

x= 3

Answer 2

Answer:

The value of x is 3.

Step-by-step explanation:

In question, it is given

4 x minus 5 y is equal to 17

which means,

4x-5y=17

x minus 5 y is equal to 8

which means,

x-5y=8

Writing these two equations,

4x-5y=17 (Equation-1)

4x-5y=17 (Equation-1)x-5y=8 (Equation-2)

Substracting Equation-2 from Equation-1 ,

we get

4x-5y-(x-5y)=17-8

4x-5y-(x-5y)=17-84x-5y-x+5y=9

4x-5y-(x-5y)=17-84x-5y-x+5y=94x-x-5y+5y=9

4x-5y-(x-5y)=17-84x-5y-x+5y=94x-x-5y+5y=93x=9

4x-5y-(x-5y)=17-84x-5y-x+5y=94x-x-5y+5y=93x=9(-5y and +5y cancels each other)

4x-5y-(x-5y)=17-84x-5y-x+5y=94x-x-5y+5y=93x=9(-5y and +5y cancels each other)x=9/3

x=3

Conclusion:

We get, Value of x is 3
