Question

d) 2+x=5
g)x/4 + 2 =7
h)x-5.3=7

Façam as contas.. Obrigada :)

Answer 1

d)
       2 + x = 5
             x = 5 - 2
                               x = 3

g)
       x/4 + 2 = 7
            x/4 = 7 - 2
            x/4 = 5
             x= 5x4
                             x = 20 

h)
         x - 5.3 = 7
         x - 15 = 7
               x = 7 + 15
                                 x = 22

Answer 2

$d) 2+x=5\to\\\\ x=5-2\to\\\\ x=3\\\\\\\\\\ g) \frac{x}{4} + 2 =7\to \\\\\frac{x}{4} =7-2\to \\\\ \frac{x}{4} =5\to\\\\ x=4*5\to\\\\ x=20\\ \\\\\\\\ h)x-5*3=7\to\\\\ x-15=7\to\\\\ x=7+15\to\\\\ x=22$
