Answer 2

Resposta:

10 (x + 1) - 5 (x - 2) = 70

10x+10-5x+10=70

10x-5x=70-10-10

5x=50

x= 50/5= 10

X= 10

5 (x + 2) - 13 = 2 (3x - 1)

5x+10-13=6x-2

5x-6x=-2-10+13

-x= 1

X= -1

7 (2 + x) = 5 (x - 1,2) + 35

14+7x=5x-6+35

7x-5x=-6+35-14

2x=15

x= 15/2

X= 7 1/2

3 (x + 1) - 2 (x - 1) = - (x + 5)

3x+3-2x+2=-x-5

3x-2x+x=-5-2-3

2x=-10

x=-10/2

X= -5

(3 + x) - 1 = (17 - 4x) - (3 + x)

3+x-1=17-4x-3-x

x+4x+x=17-3-3+1

6x=12

x= 12/6

X= 2
