Best ResponseYou've already chosen the best response.1so we can write the general formula of the nth term as below: \[{a_n} = {a_1} + \left( {n  1} \right)d\] where a1 is the first term and d=4

Best ResponseYou've already chosen the best response.1now, if we set n=10, we can write this: \[\begin{gathered}  34 = {a_1} + 9 \times \left( {  4} \right) \hfill \\ \hfill \\  34 = {a_1}  36 \hfill \\ \end{gathered} \] what is a1?

Best ResponseYou've already chosen the best response.1by definition, the second term is: \[\begin{gathered} {a_2} = {a_1} + d \hfill \\ {a_2} = 2 + \left( {  4} \right) \hfill \\ \end{gathered} \] what is a2?

Best ResponseYou've already chosen the best response.1we have to rewrite that equation in this form: ax+by=c what do you get?

Best ResponseYou've already chosen the best response.1it is a simple computation, if I multiply both sides by 4, I get this: \[\Large 4 \times \left( {\frac{x}{{  4}} + \frac{y}{1}} \right) = 4 \times 1\] please simplify

Best ResponseYou've already chosen the best response.1second question: If i sum, side by side, the first and the second equation together, I get this: \[\Large \left( {x + 3y} \right) + \left( {7x  8y} \right) = 5 + 6\] please simplify, what do you get?

Best ResponseYou've already chosen the best response.1now we have to find the solutions of this system: \[\left\{ \begin{gathered} 7x  8y = 6 \hfill \\ 8x  5y = 11 \hfill \\ \end{gathered} \right.\]
