Question

3x-5y=23 2x-4y=16solve​

Answer 1

Step-by-step explanation:

firstly we will take equation 1 and find the value of any one variable

3x=5y+23

x=5y+23/3. equation 1

lets take eq 2

we will put the value of x in this equation

2×23+5y/3-4y=16

transpose 3 to 16

and the value of y will be 2

then putting the value of y in equation 1

and the value of x will be 11

please mark me as brainliest.

Answer 2

Answer:

Given 3x-5y=23 and 2x-4y=16

now

3x-5y=23

2(3x-5y)=23(2)

6x-10y=46

and

2x-4y=16

3(2x-4y)=16(3)

6x-8y=48

6x-10y-6x+8y=46-48

-2y=-2

y=1

2x-4(1)=16

2x=16+4

2x=20

x=10
