n + 16 = 25 Subtract '16' from both sides. n + 16 - 16 = 25 - 16 Collect terms n = 9
Set up the prolem as x + 9 = 16 (with x representing the unknown number) and solve: x + 9 = 16 (then subtract 9 from each side of the equation to solve for x) x = 7 Prove the answer by substiting 7 for x: x + 9 = 16 7 + 9 = 16 16 = 16
They are: 16 amd 9
That's probably "quotient." 9 x 2 - 14/7 = 18 - 2 = 16
18
It is: 25 -9 = 16
7P + 9 = 16 + 6P subtract 6P from BOTH sides P + 9 = 16 subtract 9 from both sides P = 7
25 - 9 = 16
-5
5² = 25 4² = 16 3² = 9 25 - 16 = 9
25-16 = 9
7
52 - 32 = 25 - 9 = 16
16 - 9 = 7
They are: 16 and 9 because 16-9 = 7
25 - 9 = 16
16 - 9 = 7
