Question

agora eu quero saber espero
que vcs saibam por favor me ajudem
3 x -4 = 6 x +10
2 y - 42 = 4 y + 10 - 12
y+y+y + 4 y = 14
44 x - 2 x = 88
433 - x = 403 x - 20 x

Answer 1

3x-4=6x+10
3x-6x=10+4
-3x=14
x=-14/3

2y-42=4y+10-12
2y-42=4y-2
2y-4y=-2+42
-2y=42
y=-20

y+y+y+4y=14
7y=14
y=12

44x-2x=88
42x=88
x=44/21
$\times = 2 \frac{2}{21}$
433-x=403x-20x
-x+20x=403-433
19x=-30
x=-30/19
