if c is -1 the equation should be

4x² + 4x -1 = 0

not plus 1

I assume you want the coordinates of the zeros.

if c is indeed -1, they are at (-1.207 , 0) and (0.207 , 0)

if c is +1, as in the equation the only zero point is at (-0.5 , 0)

Pls help, i'll give you a brainliest 4 answer <3
babymother [125]

Answer:

x = 45 \ \& \ y = 5

Step-by-step explanation:

The system of linear equations in two variables is ,

\begin{cases} x = 9y \cdots (i)\\ x - 5y = 20\cdots (ii) \end{cases}

We can easily solve out this Question using substitution method . For that , substituting x = 9y from equation (i) to equation (ii) , we have ,

\implies x - 5y = 20 \\\\\implies 9y - 5y = 20 \\\\\implies 4y = 20 \\\\\implies y =\dfrac{20}{4}\\\\\implies\boxed{\boxed{ y = 5 }}

Substituting this value in (i) ,

\implies x = 9y \\\\\implies x = 9\times 5 \\\\\implies \boxed{\boxed{ x = 45 }}
