Question

Without drawing the graphs, find the points of intersection of the lines:

Answer 1

Answer:

( $\frac{18}{7}$ , $\frac{92}{21}$ ) or x = $\frac{18}{7}$ y =

( 2.57 , 4.18) or x = 2.57 y = 4.18

Step-by-step explanation:

Use elimination:  

Find the least common multiple between x or y in this case use -6 and 5 (make sure there are opposite signs)

11x - 6y = 2            multiply entire problem by 5                          

-8x + 5y = 3           multiply entire problem by 6

55x - 30y = 10        combine problems

-48x + 30y = 18

7x + 0y = 18

7x = 18 = $\frac{18}{7}$       Plug into one equation to find y

11($\frac{18}{7}$) - 6y = 2

$\frac{198}{7}$ - 6y = 2      

-6y = -$\frac{184}{7}$

y= $\frac{92}{21}$

Hope this helps :)
