Solve the system of equations below. x + y = -2
2x - y = 5

Answer choices

A. (2,-1)
B. (1,-3)
C. (9,0)

(1,-3)

Step-by-step explanation:

x+y=-2 equation(1)

x=-2-y

2x-y=5equation (2)

now ,

putting value of x in equation (2)

2x-y=5

2(-2-y)-y=5

-4-2y-y=5

-3y=5+4

-3y=9

y=-3

again,putting of value y in equation 1

x+y=-2

x-3=-2

x=-2+3

x=1

hope this will helps you

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!
