A tailor charges a basic fee of \( \$ 50 \) plus \( \$ 15.50 \) per letter to sew an athlete's name on the back of a jacket. Write a linear equation that will find the cost \( c \) to have a name containing \( x \) letters sewn on the back of a jacket.

5. Question 5. Solve \( 5 x-3=2 x+6 \)

4. Make \( c \) the subject of \( g=\frac{c+3}{4+c}-7 \)

which of the following equations is not a linear function? 1) \( 2 y-3 x=1 \) 2) \( 4 x^{2}+y^{2}=4 x y \) 3) \( y=2 \) 4) \( x=2 \)
