Answer:
$283
Step-by-step explanation:
Let,
x - for $2 notes
x + 16 - for $5 notes
EQUATION:
(x) + (x + 16) = 74
2x = 74 - 16
2x = 58
x = 29
SUBSTITUTE
x = 29 pieces of $2 notes
x + 16 = 29 + 16 = 45 pieces of $5 notes
TOTAL VALUE IS:
(29 x $2) + (45 x $5) = $283
when people say " in lowest terms" they usually mean like the simplified version of an answer
an example of this would be like
make
into lowest terms

if you dont understand comment on this and ill try to break it down more
Answer:
X=12
Step-by-step explanation:
I did this in my head but if you need the explaination tell me in the comments.
X + 1 = - 1/4 - 5/8
x + 1 = -2 - 5 / 8
x + 1 = - 7/ 8
x = -7 /8 - 1
x = - 7 - 8 / 8
x = - 15 / 8
