Answer:
<h2>C & D are both, and only correct.</h2>
Step-by-step explanation:
a.)
5x + 10 = 12
x = 2/5 NOT 5/2, so this is in fact INCORRECT.
b.)
3x + 10 = 8
x = - 2/3 NOT 2/3, This too is INCORRECT.
c.)
9x + 15 = 36
x = 7/3. This is CORRECT!
d.)
8x + 12 = 24
x = 3/2. This is CORRECT!
X-y=7
y=3x+12|-3x
x-y=7
-3x+y=12
---------------------,-
-2x=19
x=-19/2
