Question

Solve the system of equations y=-5x x+3y=28  A. Infinate Solutions B. (-6, 30) C. (44, 39) D. (-2, 10) E. No solution​

Helga · Answer

(-2,10) is the correct answer

thienan · Answer

Use substitution  Plug in -5x for y in the second equation  x + 3(-5x) = 28 x - 15x = 28 -14x = 28, x = -2 Now plug in -2 for x in first equation  Y = -5(-2) = 10  Solution: D. (-2, 10)
