Question

Kiemanh is solving the equation 15r-6r=36 . What is the value of r?

Answer 1

Answer: r = 4

Explanation:

To solve the equation 15 r - 6 r = 13, every thing is in order, all we need to do is subtract and then make r subject of the formula

15 r - 6 r = 36

9 r = 36

we then divide both-side of the equation by 9 to make r subject of the formula. Hence;

`(9r)/(9) = (36)/(9)`

(On the left hand side of the equation; 9 will cancel out 9 leaving us with r. On the right hand side of the equation 9 will divide 36 which will give us 4)

r = 4

Therefore, the value of r is 4
