1. Consider the system of equations
5x - 2y = 16,
15x - 7y = 51.
Multiply the first equation by some constant, so that in the resulting equation, the coefficient of x matches the coefficient of x in the second equation.
Enter the entire equation that results from multiplying the first equation by the constant.
2.The ordered pair (x, y)=(8, 6) is the solution of the following system of linear equations
x = 1/10y + a
y= 1/10x + b
Find the value of a + b.
3. Alice and Bob each have a certain amount of money. If Alice receives n dollars from Bob, then she will have 3 times as much money as Bob.
