Answer:
x = 72
Step-by-step explanation:
We are given the equation - 6 / 7 = - x / 84;
[tex]- 6 / 7 = - x / 84,\\- 6 * 84 = 7 * - x,\\- 504 = - 7x,\\\\x = 504 / 7 = 72,\\\\Conclusion, x = 72[/tex]
To solve this equation, we cross - multiplied the two fractions, resulting in a simplified equation so that x can be isolated.
Solution ⇒ x = 72
Answer:
x = 72
Step-by-step explanation:
[tex]-\frac{6}{7} =-\frac{x}{84}[/tex]
→ Multiply both sides by 7 to eliminate one of the fractions
[tex]-6 =- \frac{7x}{84}[/tex]
→ Multiply both sides by 84 to isolate 7x
-504 = -7x
→ Divide both sides by 7 to isolate x
-72 = -x
→ Multiply both sides by -1 to isolate the minus
72 = x
