Jiahao had 22 fewer stickers than Raju at first Then, Jiahao gave Raju 35 stickers. Now, Raju has 5 times as many stickers as Jial How many stickers did Jiahao have at first?

4. Vereinfache und berechne. a) \( \left(2^{2}\right)^{4} \) b) \( \left(x^{3}\right)^{5} \) c) \( \frac{\left(18 a^{2} b^{-6}\right)^{-2}}{\left(27 a^{3} b^{-3}\right)^{-4}} \)

Ecuación 2. \( \quad 2 \mathrm{X}+6 \mathrm{Y}=34 \) \( \Rightarrow \) Este método resuelve el sistema multiplicando las ecuaciones de tal forma que una incógnita se elimine quedando el sistema solo con una variable.

d) \( (2 x-1)^{3} \cdot(1+2 x)^{3} \)

\( 6 a b ^ { 5 } + 9 a b ^ { 5 } c + c = \)

Find the equation of the line that is perpendicular to \( y=-\frac{3}{4} x+1 \) and contains the point \( (9,12) \) \[ y=\frac{4}{3} x+[?] \]
