Solve the system of equations. \begin{aligned} & -5y-10x = 45 &-3y+10x=-5 \end{aligned} −5y−10x=45 −3y+10x=−5

x = -2

y = -5

Step-by-step explanation:

You can use either substitution or elimination for this problem. I will be using elimination,

Step 1: Add the 2 equations together

-8y = 40

y = -5

Step 2: Plug y into an original equation to find x

-3 (-5) + 10x = -5

15 + 10x = -5

10x = -20

x = -2

And you have your final answers!

46 dollars is the answer.

step-by-step explanation:

6*6 = 36,         36+10=46

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
