The value of r by solving Kiemanh equation 15r-6r=36 will be 4.
the collection of variables, factors, and mathematical calculations such as addition, subtraction, multiplication, or division that are all neutralized by the assignment operator.
The equation is a set of variable in form of a combination with each other for example 2x + 3y =9 here x and y is two variable and 2 and 3 are coefficients so it is a summation form so which mean it will be an equation.
In another example of 8x +9y =90 in this example 8 and 9 is coefficient while x and y are variable.
Given that the equation
⇒ 15r-6r=36
⇒ r(15 - 6) = 36
⇒r × 9 = 36
⇒ r = 4 hence, the correct option is 4 so the value of r will be 4.
