Q:
per \( a=-6 \) e \( b=3 \).
\( 29 a^{2}-b^{2}+a b \)
\( 30-2 m^{2}-3 n^{2}-2 m n \)
31
\( 3 \cdot(a-b)+2 \cdot(-a+b) \)
\( 32 a \cdot\left(a^{2}-b\right)-(b+2 a) \)
\( 33(5 x+6 y):(2 x-3 y) \)
\( 34-2 b-\left(-2 b^{2}+a\right) \)
\( 35-3 a \cdot(2 b-a)+(a+3) b \)
Q:
Two common strategies for solving systems of equations are graphing and subytitution, in presion
units, solving systems of linear equations has been done with these two methods Use the same
methods and apply them to the systems below.
For these systems, show how to solve algebraically and with a graph. fou may use graphing
technology if you desire.

Q:
Tog'ga sayohat yo'nalishi 4 kunga mo'ljallangan. Sayohatchilar
birinchi kun 48 km yo'Ini bosib o'tishdi, bu ikkinchi kunga
qaraganda 12 km ga ko'p. Uchinchi kun ular birinchi va ikkinoh,
kunlari umumiy yurgan yo'ldan 3 marta kam yo'l yurishdi. Agar
butun yo'nalish 153 km ni tashkil etsa, sayyohlar to 'rtinchi kun
necha km yo'l yurishgan?
