The value of r by solving Kiemanh equation 15r-6r=36 will be 4.
What is the equation?
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.
