State which method you would use to solve the following system of equations substitution, elimination) and justify your reasoning. Then solve the system. X-y=-2 2x + 4y = 38 Which method would you use? Why? Solve the system...
elimination first i would divide the second equation by -2. x - y = -2 -x- 2y = -19 the x is eliminated. -3y = -21 divide each side by -3. y = 7 plug 7 in for y to solve for x x-7 = -2 x = 5 (5,7)
