Quizplus · Accepted Answer

To solve for $x$, we need to isolate it on one side of the equation. We can do this by using the multiplication principle, which states that if we multiply both sides of an equation by the same nonzero number, the equation remains true.

In this case, we want to isolate $x$, so we can multiply both sides of the equation by 4 to get:

$$\begin{aligned} \frac{1}{4}x &= 15 \ \frac{1}{4}x \cdot 4 &= 15 \cdot 4 \ x &= 60 \end{aligned}$$

Therefore, the best choice is D, which is 60.

Solve Using the Multiplication Principle 14x=15\frac { 1 } { 4 } \mathrm { x } = 1541​x=15

Solve Using the Multiplication Principle $\frac { 1 } { 4 } \mathrm { x } = 15$
