3x + y = 2
3x²+y²+xy = 6

Step-by-step explanation:

Solve simultaneously by substitution method;

3x²+y²+xy=6---eqn1

x+y=2 square throughout the equation

X²+y²=4

Then 3(4)+xy=6 after replacing

X²+y²=4

Xy=6/12-->1/2

$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)
