Joel paid $96 for 2 pairs of pants and 4 shirts. Doug paid $168 for 3 pairs of pants and 8 shirts. Which system of equations can be used to find the cost of each pair of pants, x, and the cost of each shirt, y? Select TWO correct answers.

• 2x + 4y = 96
• 3x + 8y = 168
• 4y = 2x + 96
• 3y = 8x + 168
• 4x + 2y = 96

A system of equations is graphed on the grid. Write the system of equations in standard form that is best represented by the graph.

What is the value of y in the solution to this system of equations? 6y + x = –59 x = –2y + 9
