nlexa [21]

Answer:

The numbers are -6 and -4.

Step-by-step explanation:

$x * (x + 2) = x + 30\\x^{2} + 2x = x + 30\\x^{2} +x-30=0\\(x+6)(x-5)=0\\$

x = -6 and x = 5 (which is not negative).

How many solutions does the system of equations have? 2x + 3y = 6 y=2/3x-1 A. 0 B. 1 C. 2 D. infinite

Dvinal [7]

Answer:

The answer is B) 1.

Step-by-step explanation:

Combine the equations like this:

$2x+3y=\frac{2}{3}x-1$

Then subtract $3y$ from all sides.

$2x+3y-3y=\frac{2}{3}x-1-3y$

Simplify the equation.

$2x=\frac{2}{3}x-1-3y$

Then subtract $\frac{2}{3}x$ from all sides.

$2x-\frac{2}{3}x=\frac{2}{3}x-1-3y-\frac{2}{3}x$

Simplify again.

$\frac{4}{3}x=-1-3y$

Multiply all sides by $3$ .

$3\times \frac{4}{3}x=-3\times 1-3 \times 3y$

Simplify again.

$4x=-3-9y$

Divide all sides by $4$

$\frac{4x}{4}=- \frac{3}{4}- \frac{9y}{4}$

Simplify again.

$x= \mathbf{\frac{-3-9y}{4}}$
