Question

The equation x+9/7 =15 can be solved by performing two operations on both sides. State the operations in order of use. There may be more than one correct answer.

A. Multiply both sides by 7 first, then subtract 9 from both sides
B. Subtract 9 from both sides first, then multiply both sides by 7
C. Divide both sides by 7 first, then subtract 9 from both sides
D. Subtract 9 from both sides first, then divide both sides by 7
E. Multiply both sides by 7 first, then divide both sides by 9
F. None of the above

(b) Give the solution of the equation x+9/7 =15.
X= ?

Answer 1

E. None of the above.
The closest is A which gives
7x + 9 = 105
7x = 96 but then doesn’t find the value of x

(b) x = 96 / 7 = 13 5/7
