Answer 1

Respuesta:

1.  X = 9   3. X = 40  5. X= 18      

2. X = 8   4. X = 0

Explicación paso a paso:

$1.\\\\\\\\\\\\.$$5+\frac{x}{3} +7 = 15\\\frac{x}{3} = 15 - 5 - 7 \\\frac{x}{3} = 15 - 12\\\frac{x}{3} = 3\\x = 3 * 3 \\x= 9$                 $2.\\\\\\\\\\.$ $\frac{x+6}{2}=7\\x+6 = 7*2 \\x+6=14\\x=14-6\\x=8$

$3.\\\\\\\\\\\\\\.$$\frac{3x}{5}-4 =20 \\\frac{3x}{5}=20 + 4\\\frac{3x}{5}=24\\3x = 24*5\\3x= 120\\x= \frac{120}{3}\\x=40$                         $4.\\\\\\\\\\.$$12(x+3)=36\\x+3=\frac{36}{12} \\x+3=3\\x=3-3\\x=0$

$5.\\\\\\\\\\\\\\.$$2(\frac{x}{6}+1) = 8\\(\frac{x}{6}+1) = \frac{8}{2}\\\frac{x}{6}+1 = 4\\\frac{x}{6}=4-1\\\frac{x}{6}=3\\x=3*6\\x=18$
