Question

Qual as respostas 5X+6=-4
3x+26=-1
4x-8-2x=x-2
10x-8-2x=7x-4
2x+5-5x=-1
4x-4-5x=-6+90
3x10=2x+8+1

Answer 1

$a)5x+6=-4 \\ 5x=-4-6 \\ 5x=-10 \\ x= \frac{-10}{5} \\ x=-2$



$b)3x+26=-1 \\ 3x=-1-26 \\ 3x=-27 \\ x= \frac{-27}{3} \\ x=9 \\ \\ \\ c)4x-8-2x=x-2 \\ 4x-2x-x=-2+8 \\ 4x-3x=6 \\ x=6 \\ \\ \\ d)10x-8-2x=7x-4 \\ 10x-2x-7x=-4+8 \\ 10x-9x=4 \\ x=4 \\ \\ \\ e)2x+5-5x=-1 \\ 2x-5x=-1-5 \\ -3x=-6 \\ x= \frac{-6}{-3} x=2$



$f)4x-4-5x=-6+90 \\ 4x-5x=-6+90+4 \\ -x=88(-1) \\ x=-88 \\ \\ \\ g)3x+10=2x+8+1 \\ 3x-2x=8+1-10 \\ x=-1$

Answer 2

 

Qual as respostas

5X+6=-4 ==> 5x = - 4 - 6 ==> 5x = - 10 ==> x = - 2

3x+26=-1==> 3x = 1+26 ==> 3x=27 ==> x= 9

4x-8-2x=x-2==> 4x-2x-x=-2+8 ==> x = 6

10x-8-2x=7x-4==> 10x-2x-7x=-4+8==> x = 4

2x+5-5x=-1==> -3x = -1-5==> -3c = - 6(-1) ==> x = 2

4x-4-5x=-6+90==> 4x-5x= -6+90+4==> -x=88(-1)==> x = -88

3x10=2x+8+1  farei as duas condições


1) 3x+10=2x+8+1 ==> 3x-2x=9-10==> x = - 1

2)3x-10=2x+8+1 ==> 3x-2x=9+10==> x =  19
