I need to solve for x and y. Any help is greatly appreciated! Thank you!

Inessa05 [86]

x=-3, y=1

Step-by-step explanation:

Given equations are:

2x-3y=-9 Eqn 1

x+y = - 2 Eqn 2

From eqn 2:

$x=-y-2$

Putting x=-y-2 in eqn 1

$2(-y-2)-3y=-9\\-2y+4-3y=-9\\-5y-4=-9\\Adding\ 4\ on\ both\ sides\\-5y-4+4=-9+4\\-5y=-5\\Dividing\ both\ sides\ by\ -5\frac{-5y}{-5}=\frac{-5}{-5}\\y=1\\Putting\ y=1\ in\ eqn\ 2\\x+1=-2\\Subtracting\ 1\ from\ both\ sides\\x+1-1=-2-1\\x=-3$

Hence,

x=-3, y=1

Which situations illustrate that the sum of opposite numbers is zero?

Mrac [35]

I believe C and E, because in C, he puts in 600 then takes out 600, which equals 0. in E, they get 3000 and then spend the 3000, which also equals 0.

Hi guys i need help solving −2.4n−3 and −7.8n+2.

Airida [17]

Answer:

-5 = -5.4n

Step-by-step explanation:

- 2.4n -3 = -7.8n+2

add 2.4 to both sides

which would give you

-3 = -5.4n + 2

then you would subtract -2 from both sides

and -5 = -5.4n and this is one solution

John is living in New York, where the state sales tax is 8%. The total cost of his purchase was $50.00. What was the original pr

bogdanovich [222]

Let p be the pre-tax cost. Then 1.08p = $50. Solving for p, the pre-tax cost, we get:

p = ($50) / (1.08) = $46.30.
