Hint: you can solve for
x
and then plug it in. Or, you
could notice that (
x
+ 1)
2
=
x
2
+ 2
x
+ 1.

Hint: “6 less than
m
” is the same as
m
−
6 and the
word “product” means “multiply”.

(Estimated Difficulty Level: 2)
Hint: sometimes on the SAT, it is better
not
to solve
for
x
, especially if the question doesn’t ask you for
x
.
Here, 3(2
x
) = 2(3
x
) = 26 and 2(3
y
) = 3(2
y
) = 21, so
that 3(2
x
)
−
2(3
y
) = 5. Who cares what
x
and
y
are?

C
(Estimated Difficulty Level: 2)
Okay, perhaps this problem is a little harder than a
level 2 question. But, if you work with the answers by
plugging them in for
m
until the equation works, then
this problem is really pretty easy!

A
(Estimated Difficulty Level: 2)
Hint: if
x
2
= 4, then
x
could be either +2 or
−
2. Since
people tend to forget about the negative solution to
equations like this, the negative answer is often the cor-
rect one on the SAT.
