Which shows how to solve the equation [tex]\(\frac{3}{4} x = -8\)[/tex] for [tex]\(x\)[/tex] in one step?

A. [tex]\(\frac{4}{3}\left(\frac{3}{4}\right)x = -6\left(\frac{4}{3}\right)\)[/tex]

B. [tex]\(4\left(\frac{3}{4}\right)x = -8(4)\)[/tex]

C. [tex]\(4\left(\frac{3}{4}\right)x = -8(3)\)[/tex]

D. [tex]\(\frac{4}{3}\left(\frac{3}{4}\right)x = -8\left(\frac{3}{4}\right)\)[/tex]


Sagot :

To solve the equation [tex]\(\frac{3}{4} x = -8\)[/tex] for [tex]\(x\)[/tex], we need to isolate [tex]\(x\)[/tex].

Start with the original equation:
[tex]\[ \frac{3}{4} x = -8 \][/tex]

To isolate [tex]\(x\)[/tex], we should multiply both sides of the equation by the reciprocal of [tex]\(\frac{3}{4}\)[/tex], which is [tex]\(\frac{4}{3}\)[/tex]:

[tex]\[ \frac{4}{3} \left( \frac{3}{4} x \right) = \frac{4}{3} \left( -8 \right) \][/tex]

On the left-hand side, the [tex]\(\frac{4}{3}\)[/tex] and [tex]\(\frac{3}{4}\)[/tex] will cancel each other out, leaving us with:

[tex]\[ x = \frac{4}{3} \cdot (-8) \][/tex]

Simplify the right-hand side:

[tex]\[ x = -8 \cdot \frac{4}{3} \][/tex]

Therefore, the equation showing the correct one-step solution is:

[tex]\[ \frac{4}{3}\left(\frac{3}{4}\right) x = -8\left(\frac{4}{3}\right) \][/tex]
