Let's solve each equation step by step:<br /><br />ii) $9-4y=-5y$<br />Add $4y$ to both sides:<br />$9 = -y$<br />Multiply both sides by $-1$:<br />$y = -9$<br /><br />K) $12a-1=-a+25$<br />Add $a$ to both sides:<br />$13a - 1 = 25$<br />Add 1 to both sides:<br />$13a = 26$<br />Divide both sides by 13:<br />$a = 2$<br /><br />JI) $8+3b=-7-2b$<br />Add $2b$ to both sides:<br />$8 + 5b = -7$<br />Subtract 8 from both sides:<br />$5b = -15$<br />Divide both sides by 5:<br />$b = -3$<br /><br />M) $4n+2=6n+7$<br />Subtract $4n$ from both sides:<br />$2 = 2n + 7$<br />Subtract 7 from both sides:<br />$-5 = 2n$<br />Divide both sides by 2:<br />$n = -2.5$<br /><br />H) $2-c=5c+1$<br />Add $c$ to both sides:<br />$2 = 6c + 1$<br />Subtract 1 from both sides:<br />$1 = 6c$<br />Divide both sides by 6:<br />$c = \frac{1}{6}$<br /><br />0) $-3d-10=3d-6$<br />Add $3d$ to both sides:<br />$-10 = 6d - 6$<br />Add 6 to both sides:<br />$-4 = 6d$<br />Divide both sides by 6:<br />$d = -\frac{2}{3}$<br /><br />II) $\frac{5}{6}m+2=\frac{1}{3}m-0.8$<br />Subtract $\frac{1}{3}m$ from both sides:<br />$\frac{1}{2}m + 2 = -0.8$<br />Subtract 2 from both sides:<br />$\frac{1}{2}m = -2.8$<br />Multiply both sides by 2:<br />$m = -5.6$<br /><br />P) $-1.6-0.3p=0.9p+0.2$<br />Add $0.3p$ to both sides:<br />$-1.6 = 1.2p + 0.2$<br />Subtract 0.2 from both sides:<br />$-1.8 = 1.2p$<br />Divide both sides by 1.2:<br />$p = -1.5$<br /><br />C) $\frac{11}{12}x-\frac{2}{3}=-0.5-\frac{3}{4}x$<br />Add $\frac{3}{4}x$ to both sides:<br />$\frac{11}{12}x + \frac{3}{4}x = -0.5 + \frac{2}{3}$<br />Combine like terms:<br />$\frac{5}{4}x = \frac{1}{6}$<br />Multiply both sides by 4/5:<br />$x = \frac{4}{30} = \frac{2}{15}$<br /><br />T) $2a-(14-3a)=-10$<br />Distribute the negative sign:<br />$2a - 14 + 3a = -10$<br />Combine like terms:<br />$5a - 14 = -10$<br />Add 14 to both sides:<br />$5a = 4$<br />Divide both sides by 5:<br />$a = \frac{4}{5}$<br /><br />y) $(9-2b)-(b+5)=16$<br />Distribute the negative sign:<br />$9 - 2b - b - 5 = 16$<br />Combine like terms:<br />$4 - 3b = 16$<br />Subtract 4 from both sides:<br />$-3b = 12$<br />Divide both sides by -3:<br />$b = -4$<br /><br />(D) $-(4c-7)=5c+(11-7c)$<br />Distribute the negative sign:<br />$-4c + 7 = 5c + 11 - 7c$<br />Combine like terms:<br />$-4c + 7 = -2c + 11$<br />Add $4c$ to both sides:<br />$7 = 2c + 11$<br />Subtract 11 from both sides:<br />$-4 = 2c$<br />Divide both sides by 2:<br />$c = -2$<br /><br />X) $-6x+2(5-3x)=8$<br />Distribute the 2:<br />$-6x + 10 - 6x = 8$<br />Combine like terms:<br />$-12x + 10 = 8$<br />Subtract 10 from both sides:<br />$-12x = -2$<br />Divide both sides by -12:<br />$x = \frac{1}{6}$<br /><br />II) $4
