Answer:

Step-by-step explanation:

-5x-y=5     since its substitution, take the equation that has the    variables on

x=7y-1         opposite sides(x-7y-1) and sub in whats on the opposite side of the        

-5(7y -1)-y=5    equal sign (7y-1) in for the x variable in the first equation

-35y+5-y=5.  then you distribute the -5 to every value in the parenthesis

-36y=0          then you isolate the remaining variable on one side

y=0               then divide until the variable has no coefficiant

-5x-0=5         then you plug that value back in to the first equation

-5x=5            isolate the variable again

x=-1               then divide again. your y value is 0 and your x value is -1

Anyone know the answer?? ​
Serggg [28]

Answer:

the second option

Step-by-step explanation:

in ax²+bx+c = 0:

x = \frac{-b+-\sqrt{b^2-4ac} }{2a}

subtract both sides by 6 to get to this form, as the right side will be left with 0

6x² + 8x - 6 = 0

here, the coefficient for x² (a) is 6, the coefficient for x (b) is 8, and the remaining number added on (c) is -6

plugging our numbers into the formula, we get

x = \frac{-8+-\sqrt{(-8)^2-4(6)(-6)} }{2(6)}\\= \frac{-8+-\sqrt{64-(-144)} }{12} \\= \frac{-8+-\sqrt{208} }{12} \\ = \frac{-8+\sqrt{208} }{12} or \frac{-8-\sqrt{208} }{12}\\= 0.53518375848 or -1.86851709182\\= approximately -1.87, 0.54
