A possible fraction dawn could use is 1/6.

1/X is a better answer though where x is number of chores.

4x - 1<br> 2.<br> = x + 7<br> Can someone help please?

tatiyna

Answer:

6 $\frac{1}{3}$

Step-by-step explanation:

4x-12 = x+7

4x-12+12 = x+7+12

4x = x+19

4x-x = x+19-x

3x=19

x = 6 $\frac{1}{3}$

And if we substitute the value of x into the equation 4x-12 = x+7,

we will get 13 $\frac{1}{3}$ = 13 $\frac{1}{3}$ in the end.

Hope this helps :)
