Evaluating Linear Systems

Solve for x and y
3x + 2y = 16
7x + y = 19

Solve for x and y.
y = 2/3x - 2
y = -x + 3

Solve the system of equations by elimination.
-x + y = -13
-8x - 4y = -8 

Your family goes to a restaurant for dinner. There are 6 people in your family. Some order the chicken dinner for $14.80, and some order steak for $17. If the total bill was $91, which system best represents the situation? 

Find the solution to the system of equations: 4x - 3y = 5 and 2x + 7y = 1

A system of linear equations is represented by line $$h$$ and line $$g$$ . A table representing some points on line $$h$$ and the graph of line $$g$$ are shown. Which system of equations is best represented by lines $$h$$ and $$g$$ ? Line $$h$$ : ​ (a)   Line $$g$$ :​ ​ (b)  

8. Find the solution to the system of equations: 4x - 3y = 5 and 2x + 7y = 1

Enter the x coordinate of the solution to this system of equations.

HINT: Make sure both equations are in (x + y = #) form. Then do the shortcut.

Enter the x coordinate of the solution to this system of equations. HINT: Make sure both equations are in (y=mx+b) form. Then do the shortcut with DESMOS

Erin is 3 years younger than twice Alex's age. Their ages combined are 33 years. How old are Alex and Erin. If x=Erin's age and y=Alex's age, choose the system that matches the situation.
