Question

if in the equation 7x - y = 10 , the value of y = -3 then the value of x is​

Answer 1

Answer:

x=1

Step-by-step explanation:

7x-y=10

since y = -3

7x-(-3)=7x+3

7x+3=10

7x=10-3

7x=7

x=7/7

x=1

Answer 2

Answer:

7x - y = 10

given y=-3

that is

7x-(-3)=10

7x+3=10

7x=10-3

7x=7

x=7/7

x=1

Let's check whether it's correct or not

7×1-(-3)=10

7+3=10

10=10

L.H.S=R.H.S

hence verified
