Solve the system of equations from Problem #4. A:(4, -1)
B:(-1, -3)
C:(16, 4)
D:(9, 1)

A. (4,-1)

Step-by-step explanation:

solving by addition/elimination

2x-5y=13 *(2)

4x-10y=26

-8x+10y=-42

-4x= -16

x= 4

2(4)-5y = 13

8-5y=13

-5y=5

y= -1

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
