Step-by-step explanation:

a + a r + a r^2 + a r^3 + a r^4 + a r^5 + ar^6

a r^2 = 108

All of the steps are good up until the 25-0, instead a 0 should have put into the top and the 1 brought down so that it was 251-248 which gets you 3 as a remainder so the answer is 804 R3

_______________________________

<h3>I'm solving it using substitution method:-</h3>

<h3>7x+2y=3 {given}</h3>

<h3>=>7x=3-2y</h3>

<h3>=>x=(3-2y)/7-------(1)</h3>

<h3>x-3y=30 {given}</h3>

<h3>=>x=30+3y</h3>

<h3>=>(3-2y)/7=30+3y {putting the value of x from eqn 1}</h3>

<h3>=>3-2y=210+21y</h3>

<h3>=>3-210=21y+2y</h3>

<h3>=>-207=23y</h3>

<h3>=>y= -207/23= -9</h3>

<h3>putting the value of y on eqn(1):-</h3>

<h3>x=(3-2y)/7</h3>

<h3>x=>(3-2(-9))/7=(3+18)/7=21/7=3</h3>

<h2>Hence, x=3, y= -9</h2>

✌️✌️❤️❤️
