The correct answer is D.
Sally is 3 years younger than Ralph therefore S=R-3 which means Sally is Ralph’s age minus 3.
2x - 9x = 14 (Careful next time you accidentally added an "equal" next to the 2)
-------------------------------------
Simplify
2x-9x=<span>14
</span><span>2x+-9x</span>=<span>14
</span>--------------------------------------------
Combine the like-terms
<span>(<span>2x+-9x</span>)</span>=<span>14
</span><span><span>-7x</span></span>=<span>14
</span>--------------------------------------------------
Now divide -7 to each side
-7x ÷ -7 = 14 ÷ -7
x = -2
------------------------------------------------------
x = -2 is your answer
Well I believe the answer is A. instead of B,C, or D,
This is because you would not need to multiply right away. The problem addresses that John buys 5 more which means to add and if you needed to multiply right away it would have said twice as much or greater to for an increasive value.
Solution: 2×45+5=f
