5 Someone has attempted to solve the following equations. State whether the solution is correct (C) or incorrect (I).
a \( 5+2 x=4 x-1 \), proposed solution: \( x=3 \)
b \( 4+q=3+2 q \), proposed solution: \( q=10 \)
c \( 13-2 a=a+1 \), proposed solution: \( a=4 \)
d \( b \times(b+3)=4 \), proposed solution, \( b=-4 \)
6 State a solution to each of the following equations.
a \( 5+x=12 \)
b \( 3=x-10 \)
c \( 4 v+2=14 \)
d \( 17=p-2 \)
e \( 10 x=20 \)
f \( 16-x=x \)
g \( 4 u+1=29 \)
h \( 7 k=77 \)
i \( 3+a=2 a \)
