Question

3x - 49 =- 100

3x + 17 = 11

6x- 9 = -8 

9 x - 2 =  -11

7x + 17 = 16

Answer 1

3x - 49 =- 100
3x = -100 +49
3x = -51
x= -51/3
x= -17

3x + 17 = 11
3x = 11 -17
3x =-6
x=-6/3
x= -2

6x- 9 = -8 
6x=-8 + 9
6x = +1
x= -6/ 1
x= -6

9 x - 2 = -11
9x= -11 +2
9x =-9
x = -9/9
x=-1

7x + 17 = 16
7x = 16 - 17
7x = -1
x = -1/7
x = -0,14...

Answer 2

3x-49=-100
3x=-100+49
3x=-51
x= $\frac{-51}{3}$
x=17

3x+17=11
3x= 11-17
3x=-6
x=$\frac{-6}{3}$
x=-2

6x-9=-8
6x=-8+9
6x=1
x=$\frac{1}{6}$

9x-2=-11
9x=-11+2
9x=-9
x=$\frac{-9}{9}$
x=1

7x+17=16
7x=16-17
7x=-1
x=$\frac{-1}{7}$
