Which system of equations has a solution of approximately (0.6, –0.8)? (cont.)

Answer:Required equation is x + 2y = -1Step-by-step explanation:Given Solution: ( 0.6 , -0.8 )We have to system of equation whose solution is given.Option 1).From Solution, x = 0.6   and   y = -0.8equations: x + 2y = -1LHS = x + 2y = 0.6 + 2 × (-0.8) = 0.6 - 1.6 = -1RHS = -1LHS = RHSSo, This option is correct.Option 2).From Solution, x = 0.6   and   y = -0.8equations: 3x - y = -1LHS = 3x - y = 3 × (0.6) + (-0.8) = 2.4 - 0.8 = 1.6RHS = -1LHS ≠ RHSSo, This option is not correct.Therefore, Required equation is x + 2y = -1
