Question

sinplificar e resolver as equaçao
$2x + 5x = 14$
$5x + 5x = 50$
$6x + 6x = 36$
$2x + 2x - 3x = 1008$
$7x + 7x = 28$
$8x \div 3x - 14 = 2x$

​

Answer 1

2x+5x=14

7x=14

x=14/7

x=2

5x+5x=50

10x=50

x=50/10

x=5

6x+6x=36

12x=36

x=36/12

x=3

2x+2x-3x=1008

x=1008

7x+7x=28

14x=28

x=28/14

x=2

8x/3x-14=2x

8x/3x-2x=14

0,666666667x=14

x=20,99999999
