Solve the following system of equations. Express your answer as an ordered pair in the format (a, b) with no spaces between the numbers or symbols. 2x+7y=-7 -4x-3y=-19

For the equation below, x is the input and y is the output. y = -4x + 3 if the input is -8, then the output is

If f(x)=x+7 and g(x)=1/x what is (fog)(x)
