Sagot :

Answer:

The value of x is 12.

Step-by-step explanation:

To make the denominators the same we can: Multiply the top and bottom of each fraction by the denominator of the other.

[tex]\dfrac{x}{3}-5\cdot\dfrac{3}{3}=-1\\\dfrac{x}{3}-\dfrac{15}{3}=-1\\\dfrac{x-15}{3}=-1\\[/tex]

Cross multiply with each other.

[tex]x-15=-1\cdot 3\\x-15=-3\\x=-3+15\\x=12[/tex]

Answer:

x=12

Hope it helps

Have a nice day
