numbers -7 and 2. how are antwan's and maggie's solutions related

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}

X+y=-4 x-y=2 use elimination with adding and subtraction

Suppose that the price p, in dollars, and the number of sales, x, of a certain item follow the equation 4 p plus 4 x plus 2 pxequals56. suppose also that p and x are both functions of time, measured in days. find the rate at which x is changing when xequals2, pequals6, and startfraction dp over dt endfraction equals1.5.
