Write each equation in simplest form.

Start Fraction 7x over 8 = 21

A. 24
B. 18.375
C. 1.857
D. 19

To write the equation in simplest form, we need to isolate the variable by performing appropriate operations on both sides of the equation.

Given:

Start Fraction 7x over 8 = 21

To isolate the variable 'x', we can multiply both sides of the equation by the reciprocal of the coefficient of 'x', which is 8/7.

(8/7) * Start Fraction 7x over 8 = (8/7) * 21

This simplifies to:

x = 24

Therefore, the answer is:

A. 24

To write the equation in simplest form, we need to solve for "x" in the equation:

Start Fraction 7x over 8 = 21

To isolate "x", we can multiply both sides of the equation by the reciprocal of the fraction, which is 8/7:

Start Fraction 7x over 8 * (8/7) = 21 * (8/7)

Simplifying, the fraction cancels out, and we are left with:

x = 24

Therefore, the equation in simplest form is x = 24.

The correct answer is option A. 24.

Just type it this way:

7x/8 = 21 , fraction formatting does not work here.

multiply both sides by 8
7x = 168

take it from there
