Pregunta 6

$\frac{2x-7}{5}=3\\ 2x-7= (3)(5)\\2x-7 = 15\\2x = 15 + 7\\2x = 22\\x = \frac{22}{2} \\x = 11$

Pregunta 7

$\frac{8x+1}{3}=3\\ 8x+1= (3)(3)\\8x+1=9\\8x = 9 -1\\8x = 8\\x = \frac{8}{8} \\x= 1$

Pregunta 8

$3(x+7)=10x\\3x + 21 = 10x\\21= 10x - 3x\\21 = 7x\\\frac{21}{7}=x\\ x = 3$

Pregunta 9

$3(5x-4)=6x+11-5\\15x-12=6x+6\\15x - 6x = 6 + 12\\9x =18\\x = \frac{18}{9} \\x=2$

Pregunta 10

$17+5(x-2)=11+2(2x+1)\\17+5x-10=11+4x+2\\7 + 5x = 13 + 4x\\5x - 4x = 13 - 7\\x = 6$

Resuelve

$x+79 = 83\\x = 83 -79\\x = 4$
