Answer 2

Let's solve each equation step by step:

1. $X - 5 + 350 = 1350$

   To solve for $X$, you can start by moving the constants to the other side of the equation:

   $X - 5 + 350 - 350 = 1350 - 350$

   $X - 5 = 1000$

   Now, add 5 to both sides to isolate $X$:

   $X - 5 + 5 = 1000 + 5$

   $X = 1005$

   So, $X = 1005$.

2. $X + 880: 20 = 1050$

   To solve for $X$, you can multiply both sides by 20 to isolate (X):

   $20(X + 880: 20) = 20(1050)$

   $X + 880 = 21000$

   Now, subtract 880 from both sides:

   $X + 880 - 880 = 21000 - 880$

   $X = 20120$

   So, $X = 20120$.

3. $24(x + 9) = 288$

   To solve for $x$, divide both sides by 24:

   $\frac{24(x + 9)}{24} = \frac{288}{24}$

   $x + 9 = 12$

   Now, subtract 9 from both sides to isolate $x$:

   $x + 9 - 9 = 12 - 9$

   $x = 3$

   So, $x = 3$.

4. $124:(y-5) = 31$

   To solve for $y$, multiply both sides by $y - 5$:

   $124 = 31(y - 5)$

   Now, divide both sides by 31:

   $\frac{124}{31} = \frac{31(y - 5)}{31}$

   $4 = y - 5$

   Add 5 to both sides to isolate $y$:

   $4 + 5 = y - 5 + 5$

   $y = 9$

   So, $y = 9$.
