Question

9/10 times a number plus 6 is 51

Answer 1

(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

Answer 2

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
