Solve the system of equations using any method. 6x + 4y = −8 4x − 2y = 2 a) ( 11 7 , 2 7 ) b) ( 2 7 , 11 7 ) c) (− 2 7 , 11 7 ) d) (− 2 7 , − 11 7 )

it happens during combustion and impacts the environment because the plants and trees take in that and it can cause them to die.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
