I’m doing elimination and my problem is
2x-4y=32
7x+6y=-8

x=4,y=-6

Step-by-step explanation:

2x-4y=32 ――――equ 1

7x+6y=-8 ――――equ 2

multiply equ 1 by 6 which is the co-efficient of y in equ 2, so vice verser for equ 2

2x-4y=32 ――――equ 1 multiply 6

7x+6y=-8 ――――equ 2 multiply 4

12x-24y=192

28x+24y=-32

40x=160

x=4 ――――equ 3

so put 4 in x in any equation but i choose equ 1

2x-4y=32

2（4）-4y=32

8-4y=32

collect like term

-4y=32-8

-4y=24

y=-6

the probability that a bird is green (.30) is true

step-by-step explanation:

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
