Y=2x-1. 5x+4y=22 use substitution to solve

If 1 is divided by the sum of y& 4. the result is equal to 3 divided by 4 .find the value of m?

Let the closed interval [a , b] be the domain of function f. the domain of f(x - 3) is given by (a) the open interval (a , b) (b) the closed interval [a , b] (c) the closed interval [a - 3 , b - 3] (d) the closed interval [a + 3 , b + 3]

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