Question

Presciso da 22 Até 12:30.Obrigada.Beijão.

Answer 1

a) x + 15 = 11
    x = 11 - 15
    x = - 4

b) 19x = 266
    x = 266/19
    x = 14

c) x/13 = -2
    x = -2.13
    x = - 26

d) 1,5x - 6 = 0
    1,5x = 6
    x = 6/1,5
    x = 4

e) 1,5x + 4 = 19
    1,5x = 19 - 4
    1,5x = 15
    x = 15/1,5
    x = 10

f) x/5 - 3 = 10
   x/5 = 10 + 3
   x/5 = 13
   x = 13.5
   x = 65

Answer 2

a)x+15=11
x=11-15
x=-4

b)19x=266
x=266/19
x=14

c)x/13=-2
x-2.13
x=-26

d)1,5x-6=0
1,5x=6
x=6/1,5
x=4

e)1,5x+4=19
1,5x=19-4
1,5x=15
x=15\1,5
x=10

f)x\5-3=10
x\5=10+3
x\5=13
x=13.5
