Answer:

r = 2

Step-by-step explanation:

I'm assuming we're finding r

11 = 1 + 3r + 2r

Add up the numbers with r

11 = 1 + 5r

Subtract both sides by 1

11 = 1 + 5r

-1 -1

10 = 5r

Divide both sides by the coefficient, 5, to isolate the variable, r

10/5 = 5r/5

r = 2

Which number can each term of the equation be multiplied by to eliminate the fractions before solving?

scoray [572]

Answer: 12

Step-by-step explanation:

You can multiply by 12 because to get rid of the fractions all terms should be divided by the LCM (ie the smallest multiple that is exactly divisible by 2, 4 and 3)

Multiples of 3 = 3, 6, 9, 12

Multiples of 4 = 4, 8, 12, 16

Multiples of 2 = 2, 4, 6, 8, 10, 12

Therefore the fractions should be multiplied by 12
