Answer:

[tex]x < 2[/tex]

Step-by-step explanation:

We want to solve the inequality

[tex] \frac{ - 10 + x}{4} + 5 > \frac{7x - 5}{3} [/tex]

We multiply through by 12 to get:

[tex]12 \times \frac{ - 10 + x}{4} +12 \times 5 > \frac{7x - 5}{3} \times 12[/tex]

We simplify to get

[tex]3(- 10 + x) +60>4(7x - 5)[/tex]

We expand to get:

[tex] - 30 + 3x +60>28x - 20[/tex]

Group similar terms to get

[tex]- 30 +60 + 20>28x - 3x[/tex]

[tex]50 > 25x[/tex]

[tex]2 > x[/tex]

[tex] x< 2[/tex]
