Solve the following word problem. Please show all of your work. "I have 4 more pairs of shoes than my sister. Together, we have 20 pairs of shoes.
How many pairs of shoes does my sister have?"

ANSWER: 8

(I think)

Step-by-step explanation:

I kinda just counted it cant be more than 11 because if u have 4 more than it would be 11+15=26 too much and so is ten (both equations show why there too much) 10 10+14=24. Lets try 8 8+12=20 so your sis has 8 pairs

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
