4x + 5x + 12 = 6(x-2) Math

Rashid [163]

Hi there! :)

$\large\boxed{x = -8}$

4x + 5x + 12 = 6(x - 2)

Combine like terms and distribute the coefficient outside of the parenthesis:

9x + 12 = 6(x) + 6(-2)

9x + 12 = 6x - 12

Subtract 6x from both sides:

9x - 6x + 12 = 6x - 6x - 12

3x + 12 = -12

Subtract 12 from both sides:

3x + 12 - 12 = -12 - 12

3x = -24

Divide both sides by 3:

3x/3 = -24/3

x = -8.

Let x be the percentage of p.
Therefore,
$m\% \: \: of \: \: n = x\% \: \: of \: \: p \\ = > \frac{mn}{100} = \frac{px}{100} \\ = > mn = \frac{px}{100} \times 100 \\ = > mn = px \\ = > \frac{mn}{p} = x$

Answer:

$\frac{mn}{p}$

Hope you could get an idea from here.

Why do you think it's important that we always label our units on word problems

MAXImum [283]

Word problems describe a situation where something mathematical can be found out about a system. Often, it's a real-world measurement (like numbers of apples, ages of people, inches, feet, etc.) and usually have more than one object being discussed.
The answer must be expressed in specific units so the value cannot be confused with other measurements discussed in the problem.
