Solve the system of equations given below. (Please--help..)

Step-by-step explanation:

x+2y=-4

2x+3y=1

The difference between this two equations is x+y so:

x+y

=1-(-4)

=1+4

=5

I'm not sure what the question is asking to find, but I have already helped you find the value of x+y, good luck with the rest I guess :))

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
