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
