Answer 2

It looks like you have a set of equations. Let's solve each of them step by step:

1. $2x - 200 = 700$ To solve for $x$, you can follow these steps: Add 200 to both sides: $2x = 900$ Divide both sides by 2: $x = 450$ So, the solution is $x = 450$.

2. $160 : (y + 5) = 20$ To solve for $y$, follow these steps: Multiply both sides by $y + 5$: $160 = 20(y + 5)$ Divide both sides by 20: $8 = y + 5$ Subtract 5 from both sides: $y = 3$ So, the solution is $y = 3$.

3. $\frac{12m - 5m}{14} = 4$ Combine the terms in the numerator: $\frac{7m}{14} = 4$ Divide both sides by $\frac{7}{14}$, which is 1: $m = 4$ So, the solution is $m = 4$.

4. $132 - 9(x - 5) = 69$ Distribute the -9 on the left side: $132 - 9x + 45 = 69$ Combine constants: $177 - 9x = 69$ Subtract 177 from both sides: $-9x = -108$ Divide both sides by -9: $x = 12$ So, the solution is $x = 12$.

To recap the solutions:

1. $x = 450$
2. $y = 3$
3. $m = 4$
4. $x = 12$
