Answer:
A
= 
b =
× 
b = 
then b =
that is ORANGE
B
-2 - v = -7
v = -7 +2
then v = k + m that is BROWN
C
= 
q = 
then q =
that is YELLOW
D
4m + 2(n) = 5 (n)
4m = 5 (n) - 2n
4m = 3n
m = 
then m =
that is RED
E
-8 =
- 6
= -8 + 6
x = -5 (-8 + 6)
then x = y( w + z ) that is LIGHT GREEN
-4+x=9.5
x=13.5
The student might have subtracted 9.5-4, which results in the answer 5.5. The correct answer is 13.5.
