2. Two leaking water containers have a total capacity of 760 . If they both leak 204 per hour, find the capacity of each container If one of the containers have 4 times the amount of water than the other after 9 hours.

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

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

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) \( x=2 \)

\( 3 x-2 y=7 \) (1) \( y+2 y=14 \) (2)

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