reais a seguinte equação: (2x - 5) = (x-7)​

Answer 1

Resposta:

)X=\frac{4}{2} = 2X=24=2

b)X=\frac{9}{3}=3X=39=3

c)X=\frac{16}{2}=8X=216=8

d)X=\frac{625}{5}=125X=5625=125

e)X=\frac{100000}{10}=10000X=10100000=10000

f)X=\frac{1}{12}X=121

g)X= \frac{\frac{1}{125}}{5}=\frac{1}{625}X=51251=6251

h}X= \frac{\frac{1}{1024}}{2}= \frac{1}{2048}X=210241=20481

j)X=\frac{\frac{1}{9}}{\frac{1}{27}} = \frac{27}{9} = 3X=27191=927=3

Answer 2

Resposta:

2x-x=-7+5

x= -2
