Answer:
The answer is "[tex]\frac{26}{7}[/tex]"
Step-by-step explanation:
The whole question can be found in the file attached.
[tex]\to x + \frac{5}{7} = \frac{31}{7}\\\\[/tex]
Subtracting the [tex]\frac{5}{7}[/tex] from both sides of the equations:
[tex]\to x +\frac{5}{7} - \frac{5}{7} = \frac{31}{7} - \frac{5}{7} \\\\[/tex]
[tex]= \frac{31-5}{7} \\\\= \frac{26}{7} \\\\[/tex]
