Question

B) 1-3x/2 + x+7/3 + 5-2x/4

2. A) x/2-3+2x/5=x/4
B) x+2/2 -2. (2 - x) = x - 5x+14/6

C) 2. (X-2) +3x/4 - x-3 .(2x+9)/5 + x+4/10 = 7x/20 +2x

Answer 1

Resposta:letra b a)9x-2= 4x+18

9x-4x=18+2

5x=20

x= 20/5

x=4

2x-10+7x+10=180

9x=180

x=180/9

x=20

7y-10= y+50

7y-y=50+10

6y= 60

y= 60/6

y=10

4x-18+3x=10

3x+4x=10+18

7x=28

x=28/7

x=4

2x+5+x+7=18

2x+x= 18-5-7

3x= 6

x=6/3

x=2

5x-91=4x-77

5x-4x=-77+91

x= 14

7x+1=5x-7

7x-5x=-7-1

2x= -8

x=-8/2

x= -4

4x+5=x+20

4x-x= 20-5

3x= 15

x=15/3

x=5
