Solve simultaneously for \( x \) an \[ x(x-3)+y(3-x)=0 \]

Add \( 5 \mathrm{a}-3 \mathrm{~b} \) and \( -5 \mathrm{~b}+3 \mathrm{a} \) the result is ...... \[ \begin{array}{l}8 \mathrm{a}-8 \mathrm{~b} \\ 8 \mathrm{a}+8 \mathrm{~b} \\ 8 \mathrm{~b}-8 \mathrm{a} \\ 2 \mathrm{a}-2 \mathrm{~b}\end{array} \]

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) \( x=2 \)

a \( \quad 2^{3} \cdot 2^{-4} \)

question 4. Solve \( 3 x+2=2+4 x \)
