Question

a) x/2-7=x/4+5

b) 2x- 1/2= 5x+ 1/3

c) x-1= 5- x/4

d) x/6+ x/3= 18 - x/4

e) x/4 + x/6 + x/8 = 26

f) x/8 + x/5 = 17 - x/10

Answer 1

$a) \frac{x}{2-7}= \frac{x}{4+5} \\\frac{x}{-5}= \frac{x}{9} \\9x=-5x\\14x=0\\x=0\\\\b)2x-\frac{1}{2} =5x+\frac{1}{3} \\-\frac{1}{3}- \frac{1}{2}=3x\\\\-\frac{5}{6} =3x\\x=-\frac{5}{2} \\c)x=1=5-\frac{x}{4}\\\frac{5x}{4} =6\\\\x=\frac{24}{5} \\d) \frac{x}{6}+\frac{x}{3} =18-\frac{x}{4}\\\frac{x}{4}+ \frac{x}{6} +\frac{x}{3} =18\\\frac{9x}{12} =18\\x=\frac{216}{9} \\x=24\\e)\frac{x}{4}+ \frac{x}{6} +\frac{x}{8} =26\\\frac{13x}{24} =26\\x=\frac{624}{13} \\x=48$
