Question

The difference between two number is 3. Write the data in form of linear equation in two variables. Also, represent it graphically.If smaller number is 8, then find graphically the value of larger number.

Answer 1

let x larger number
y smaller number
linear equation
x-y = 3
if y =8
x -8 = 3
x = 3+8 = 11

Answer 2

let the bigger number be 'x'

in an equation,
x - 8 = 3

transpose -8 to the RHS of the equation.

x = 3+8
x = 11

the value of larger number is 11.
