Question

AYUDAAAA!!!

10Y +5 = 5Y + 20

3 (2Y + 4) = 9Y - 12

21 - 6m =27 - 8m

8m - 4 + 3m = 7m + m +14

n + 5 - 4n + 7 = 5n + 14

-17 + 12z - 8z + 2 =1

AYUDA URGENTEEE :( MI MAMA ME VA A PEGAR POR BRUT4 :(((( NESESITO EL PROCESO Y VERIFICACION DE CADA UNA DE ESAS ECUACIONES PLIISSSSSS AYUNDEME A GANAR LA MATERIAAAAA AAAHH!!!

Answer 1

Respuesta:

10Y +5 = 5Y + 20

$10Y=25Y$

3 (2Y + 4) = 9Y - 12

$6Y+12=9Y-12\\\\6Y+12-12=9Y-12-12\\\\6Y=9Y-24\\\\6Y-9Y=9Y-24-9Y\\\\-3Y=-24\\\\\frac{-3Y}{-3}=\frac{-24}{-3}\\\\Y=8$

21 - 6m =27 - 8m

$21-6m-21=27-8m-21\\\\-6m=-8m+6\\\\-6m+8m=-8m+6+8m\\\\2m=6\\\\\frac{2m}{2}=\frac{6}{2}\\\\m=3$

8m - 4 + 3m = 7m + m +14

$8m+3m-4=7m+m+14\\\\11m-4=7m+m+14\\\\11m-4=8m+14\\\\11m=8m+18\\\\11m-8m=8m+18-8m\\\\3m=18\\\\\frac{3m}{3}=\frac{18}{3}\\\\m=6$

n + 5 - 4n + 7 = 5n + 14

$n-4n+5+7=5n+14\\\\-3n+5+7=5n+14\\\\-3n+12=5n+14\\\\-3n+12-12=5n+14-12\\\\-3n=5n+2\\\\-3n-5n=5n+2-5n\\\\-8n=2\\\\\frac{-8n}{-8}=\frac{2}{-8}\\\\n=-\frac{1}{4}$

-17 + 12z - 8z + 2 =1

$-17+4z+2=1\\\\4z-17+2=1\\\\4z-15+15=1+15\\\\4z=16\\\\\frac{4z}{4}=\frac{16}{4}\\\\z=4$

espero que no te peguen >"<
