Verified answer

Ответ:

a) x=14

б) у= 13

Объяснение:

а)

[tex] \frac{x}{2} - \frac{x + 4}{3} = 1 \\ 3x - 2(x + 4) = 6 \\ 3x - 2x - 8 = 6 \\ x - 8 = 6 \\ x = 14[/tex]

б)

[tex] \frac{y - 3}{5} + \frac{y + 3}{4} = 6 \\ 4(y - 3) + 5(y + 3) = 120 \\ 4y - 12 + 5y + 15 = 120 \\ 9y + 3 = 120 \\ 9y = 117 \\ y = 13[/tex]
