Solve the literal equation for the given variable<br> n =4/5(m+7); m

Step2247 [10]

Answer:

Step-by-step explanation:

First of all multiply both sides by 5

That's

<h3> $5n = 5 \times \frac{4}{5} (m + 7) \\ 5n = 4(m + 7)$ </h3>

<u>Next divide both sides by 4</u>

That's

$m + 7 = \frac{5n}{4}$

Subtract 7 from both sides to make m stand alone

Answer:

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

Explanation:

→ $\frac{(x^2-9)(x+2)}{(3x^2 +8x -3)(x-3)}$

→ $\frac{\left(x+3\right)\left(x-3\right)\left(x+2\right)}{\left(3x^2+8x-3\right)\left(x-3\right)}$

→ $\frac{\left(x+3\right)\left(x+2\right)}{3x^2+8x-3}$

→ $\frac{\left(x+3\right)\left(x+2\right)}{\left(3x-1\right)\left(x+3\right)}$

→ $\frac{x+2}{3x-1}$
