Question

qual a resposta : 9x=18 , 35x=-105, 7x-1=13, 6x-10=2x+14, 6x=2x+28 me ajdemmmmm pleasseee

Answer 1

9x=18
x = $\frac{18}{9}$
x = 2

-> 35x=-105
x = - $\frac{105}{35}$
x = - 3

7x-1=13
7x = 13 + 1
7x = 14
x = $\frac{14}{7}$
x = 2

6x-10=2x+14
6x - 2x = 14 + 10
4x = 24
x = $\frac{24}{4}$
x = 6

6x=2x+28
6x - 2x = 28
4x = 28
x = $\frac{28}{4}$
x = 7

Answer 2

$9x=18\to x= \frac{18}{9} \to x=2\\\\\\\\\\ 35x=-105\to x= \frac{-105}{35} \to x=-3\\\\\\\\\\7x-1=13\to 7x=13+1\to 7x=14\to x= \frac{14}{7} \to x=2\\\\\\\\\\ 6x-10=2x+14\to 6x-2x=14+10\to 4x=24\to x= \frac{24}{4} \to x=6\\\\\\\\\\ 6x=2x+28\to 6x-2x=28\to 4x=28\to x= \frac{28}{4} \to x=7$
