9/10 times a number plus 6 is 51

First we put the sentence into a function

9/10 * x + 6 = 51Well then we solve. 9/10 * x = 51-6

9/10*x = 45

(for me is easier to make the fraction into a decimal ...)

0.9*x = 45

x=45/0.9

x = 50

We check

9/10 * 50 + 6 = 51

45+6=51

51=51

So the answer is x = 50

(9/10) X + 6 = 51 Subtract 6 from both sides (Subtraction property of equality) (9/10) X = 45 Divide by (9/10) (division property of equality) The answer is : 50
