Question

resolva as equações a) 3x - 1 /5 =4 b) 19x = 266 c) x/13 = -2 d) 1,5x - 6 = 0 e) 1,5x + 4 = 19 f) x/5 - 3 = 10 coloquem as contas pra me ajudem

Answer 1

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
