It's a simple linear equation in 'n'. There's only one number that 'n' can be
that will make the equation a true statement. That number is called the
'solution' to the equation. Here's one way to find it:

You said that  -7n - 4 = 24

Add 4 to each side: -7n = 28

Multiply each side by -1 : 7n = -28

Divide each side by 7 : n = -4

Homework is the only way for most people to learn stuff.

Answer/Step-by-step explanation:

Quotient is simply the ratio of the first numerator to the second numerator:

Let's $\frac{x_1}{y}\;and\;\frac{x_2}{y}$ are two fractions in same terms.

Thus, $\frac{x_1}{y}\div\frac{x_2}{y}$ {Divided by a fraction is equal to multiplied by its reciprocal}

= $\frac{x_1}{y}\times\frac{y}{x_2}$

Quotient is simply the quotient of their numerators.

Example could be:

$\frac{2}{7}\div\frac{3}{7}$

$\frac{2}{7}\times\frac{7}3}$

$\frac{2}{3}$

2 is first numerator and 3 is the second numerator.

Solve the quadratic equation: 3x2 + x - 5 = 0

Yuri [45]

Hey there!

$3x^2 + x -5 = 0$

This equation is in standard form, which is $ax^2+bx+c=0$ .

We are going to solve this with the quadratic equation, so we need to find the values for a, b, and c in the given equation. We can just look at it and identify the variables.

a = 3, b = 1, c = -5

Let's plug these values into the quadratic equation:

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