Question

solve in linear equation in two variable x+7y=10;3x-2y=7​

Answer 1

Answer:

y=1,x=3 is the correct answer.

Step-by-step explanation:

x+7y=10

3x-2y=7

by equation 1

x=10-7y

put the value of x in 2nd equation.

3x-2y=7

3(10-7y)-2y=7

30-21y-2y=7

30-23y=7

-23y=7-30

-23y=-23

y=1

put the value of y in equation 1st.

x+7y=10

x+7(1)=10

x+7=10

x=10-7

x=3
