Solve the system of equations by first multiplying. ſ 3x +y = -5
1 2x + 5y = 27
Write the solution as an ordered pair.

3x+y=-5

12x+5y=27

Let y =-5-3x

Insert y into equ.2

12x+5(-5-3x)=27

12x-25-15x=27 den rearrange

-3x=2 den x =-2/3

Den put xinto equ 1

3(-2/3)+y=5

-2+y=5(collect like terms)

Y =7

step-by-step explanation:

mean or average is 40.6

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
