Question

Rezolvati ecuatiile :
a. $125 + \frac{x}{4} - \frac{1}{4} = 200$
b.$(3 \frac{1}{8} -x ) - 1 \frac{1}{10} =0$
c. $x- \frac{2}{3} - \frac{5}{6} = \frac{1}{2}$

Answer 1

a)
125+x/4-1/4=200
500+x-1=800
x=301

b)
 3 1/8-x-1 1/10 =0
25/8-x-11/10=0
250-80x-88=0
80x=162
x=162/80
x=81/40

c)
x-2/3-5/6=1/2
6x-4-5=3
6x=12
x=2
