I just need the bottom

What is the solution to this system of equations? y= 2x - 3.5 x - 2y = -14

3/4 + p = 1/2? i’m not sure how to solve it

A) find the derivative of the inverse to f(x) = 3x + sint at x 6. b) (cale) find the derivative of the inverse to f(x)+3sin at x 6. if x +2y -34, ind he behaviar of the cure at 4,.3), c) a. increasing, concave up d. decreasing, concave down b. increasing, concave down e. decreasing, inflection point c. decreasing, concave up
