Answer 2

To solve these equations, I'll go through them one by one:

1. $1)(x-16)-9-126$:

   Start by simplifying the equation: $x - 16 - 9 - 126$

   Combine like terms: $x - 151$

2. $28(x + 5) - 224$:

   Distribute 28 to both terms inside the parentheses: $28x + 140 - 224$

   Combine like terms: $28x - 84$

3. $(x + 76)/7 - 15$:

   First, simplify the expression inside the parentheses: $(x/7 + 76/7) - 15$

   Now, combine the fractions: $(x/7 + 76/7) - 15$

   To subtract 15, you can convert it into a fraction with a common denominator of 7: $(x/7 + 76/7) - (15 * 7/7)$

   Simplify the expression further: $(x/7 + 76/7 - 105/7)$

   Combine like terms: $(x/7 - 29/7)$

4. $144 / (x-3) = 36$:

   First, divide both sides by 36 to isolate the fraction on the left side: $\frac{144}{36} = \frac{x - 3}{36}$

   Simplify: $4 = \frac{x - 3}{36}$

   To solve for $x$, multiply both sides by 36: $4 * 36 = x - 3$

   $144 = x - 3$

   Now, add 3 to both sides to isolate $x$: $144 + 3 = x$

   $147 = x$

5. $21 - (y - 8) = 84$:

   To solve for $y$, first simplify the equation by distributing the negative sign: $21 - y + 8 = 84$

   Combine like terms on the left side: $29 - y = 84$

   Now, subtract 29 from both sides to isolate $y$: $-y = 84 - 29$

   $-y = 55$

   Finally, multiply both sides by -1 to solve for $y$: $y = -55$

6. $(x + 67) / 18 = 4$:

   To solve for $x$, first multiply both sides by 18 to isolate the fraction on the left side: $18 * \frac{x + 67}{18} = 4 * 18$

   Simplify: $x + 67 = 72$

   Now, subtract 67 from both sides to isolate x\: \(x = 72 - 67

   $x = 5$

So, the solutions are:

1. $x - 151$
2. $28x - 84$
3. $(x/7 - 29/7)$
4. $x = 147$
5. $y = -55$
6. $x = 5$
