The difference between two numbers is 9. The first number plus twice the other numberis 27. Find the two numbers. is the smaller number is the larger number Solve the system of equations by graphing. ( , ) y= -2x + 2 y = 7x + 11 Solve the system of equations using substitution. ( , ) y = 2x 5x - y = 9 Solve the system of equations using elimination. ( , ) x - 3y = 16 4x - y = 9 Solve the system of equations. y = 2x + 1 2x - y = 3 (1, 3) (5, 7) Infinite Solutions No Solution  What is the solution to the system graphed below? ( , ) Solve the system of equations. ( , ) x + 2y = -2 3x + 4y = 6 Rob has $1.65 in nickels and dimes. He has 25 coins in all. How many of each kind of coin are there? nickels dimes  Graph 1 Graph 2 Graph 3 Graph 4 Which system of equations has a solution of (2, 2)?  Write the system of equations shown on the graph below. green line: red line: y = x y = x (Include operation symbols/signs and nospaces) Solve the system of equations. 4y = 2x - 8 5x - 4y = 20 ( , ) Solve the system of equations. ( , ) y = x + 8 x + y = 2 If using elimination to solve, what should the first equation be multiplied by in order to eliminate x? x - 3y = 16 4x - y = 9 |
