He solution to the system of equation below is (? 2, ? 1). 2x ? 3y = ? 1 11x ? 9y = ? 13 when the first equation is multiplied by ? 3, the sum of the two equations is equivalent to 5x = ? 10. which system of equations will also have a solution of (? 2, ? 1)? (a)5x = ? 10 11x ? 9y = ? 13 (b)2x + 9y = ? 1 11x ? 9y = ? 13 (c)? 6x + 9y = ? 1 11x ? 9y = ? 13 (d)? 6x + 3y = ? 1 5x = ? 10

the reason why your question keeps getting deleted because this is not a school related question : )

i will answer your question though.

i never tried church's

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
