It looks like you've provided a list of mathematical equations. It seems you want help solving these equations for their respective variables. Let's go through each equation step by step:

1. $(12x - 5x) \times 4 = 252$ Simplify: $7x \times 4 = 252$ $28x = 252$ Divide both sides by 28: $x = \frac{252}{28} = 9$

2. $(4y + 3y) \times 11 = 1543$ Simplify: $7y \times 11 = 1543$ $77y = 1543$ Divide both sides by 77: $y = \frac{1543}{77} = 20$

3. $\frac{45}{4x - x} = 34$ Simplify the denominator: $\frac{45}{3x} = 34$ Multiply both sides by $3x$: $45 = 102x$ Divide both sides by 102: $x = \frac{45}{102} = \frac{15}{34}$

4. $\frac{19y - 6y}{4} = 265$ Simplify the numerator: $\frac{13y}{4} = 265$ Multiply both sides by 4: $13y = 1060$ Divide both sides by 13: $y = \frac{1060}{13} \approx 81.54$

5. $\frac{16x + 5x}{18} = 76$ Simplify the numerator: $\frac{21x}{18} = 76$ Multiply both sides by 18: $21x = 1368$ Divide both sides by 21: $x = \frac{1368}{21} \approx 65.14$

6. $(17y - 8y) \times 13 = 3517$ Simplify: $9y \times 13 = 3517$ $117y = 3517$ Divide both sides by 117: $y = \frac{3517}{117} \approx 30.04$

7. $25x - 16x + 54 = 1628$ Simplify: $9x + 54 = 1628$ Subtract 54 from both sides: $9x = 1574$ Divide both sides by 9: $x = \frac{1574}{9} \approx 174.89$

8. $14y + 9y + 88 = 2729$ Simplify: $23y + 88 = 2729$ Subtract 88 from both sides: $23y = 2641$ Divide both sides by 23: $y = \frac{2641}{23} \approx 114.83$

9. $15x + 8x - 59 = 102$ Simplify: $23x - 59 = 102$ Add 59 to both sides: $23x = 161$ Divide both sides by 23: $x = \frac{161}{23} \approx 7$

10. $\frac{y + 79}{7} = 12$ Multiply both sides by 7: $y + 79 = 84$ Subtract 79 from both sides: $y = 5$

So, the solutions are approximately:

1. $x \approx 9$
2. $y \approx 20$
3. $x \approx \frac{15}{34}$
4. $y \approx 81.54$
5. $x \approx 65.14$
6. $y \approx 30.04$
7. $x \approx 174.89$
8. $y \approx 114.83$
9. $x \approx 7$
10. $y=5$ 0 0
