10) What is the solution to the system of equations shown below?

2x+y=10 and 4x+3y=15

A (2.5,-5) B (7.5,-5) C (-5,20) D (-5,0)

wORK SHOWN PLEASE :)

B

X= 7.5

Y= -5

Step-by-step explanation:

In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.

I will upload a picture showing my work.

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
