Question

por favor gente me ajuda​

Answer 1

Resposta:

a) S={4}

b) S={1/2}

c) S={3}

d) S={9,6}

Explicação passo-a-passo:

a) x-4-x+4/3=0

3(x-4)-x+4=0/3

3x-12-x+4=0

2x=8

x=4

b) 4x/3- 3/2= x-3/3

8x-9/6= x-3/3

3(8x-9)= 6(x-3)

x=1/3

c) 3-x/8= x+1/4 - x/3

3-x/8= 3(x+1)-4x/12

3-x/8= -x+3/12

36-12x= -8x + 24

x=3

d) t-5/2- 1/3= t/3-3t+14/12

3(t-15)-2/6= 4t-3t+14/12

3t -15 - 2/6= t + 14/12

t=9,6
