S)x-2/3-x+1/4=4
T)x/3+x/2=7+x/3​

ME AJUDEM POR FAVOR​

Answer 1

Resposta:

P) x/2+x/4+x/2=4

x/2+x/2=4-x/4

2x/2=4-(x/4)

x=16/4-(x/4)

x=15x/4

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

3x/4- 2x/4=-2

x/4=-2

x=-8

R)x-1/2+x+1=6

2x=6-1+1/2

2x=5+1/2

x=11/2÷2

x=11/2×1/2

x=11/4

S) x-2/3-x+1/4=4

-2/3+1/4=4

-8/12+3/12=4

-5/12 = 4 ????? Não é verdadeira

a equação!!!

T) x/2=7

x=14
