Question

The equation x = 7 in two variables can be written as -
(a)1.x + 1.y=7
(b)1.x+ 0.y=7
(c)0.x + 1.y = 7
(d)p.x+ 0.y=7​

Answer 1

Here, y variable is missing so we take 0.y

For x, we take value 1 since no digit is mentioned. So, 1.x

According to these , option B goes with the solution.

So answer will be : 1.x + 0.y = 7

Answer 2

Answer:

a) 1.x +1.y =7

Step-by-step explanation:

. verbiables can change their values from time to time depending upon the equation.

. Here, X and Y are two variables,

. when any number variable or constant is multiplied by 0 then it became 0.

. when we multiply 1 by x we get, x

similarly, when we multiply 1 by Y we get,

both are variables.

. The required answer is, 1.X + 1.Y =7
