Question

1)- $frac{5}{6}$в=0,5 2)7х=3,5 3)2у-$frac{5}{8}$=1 4)$frac{3}{4}$+$frac{2}{3}$х=$frac{1}{2}$ 5)- $frac{5}{6}$а=$frac{2}{3}$а+2

Answer 1

(5/6)b=0.5=1/2
b=1/2:5/6=6/10=3/5

7x=3.5
x=3.5/7=0.5

2y-5/8=1
2y=1+5/8=13/8
y=(13/8):2=13/16

3/4+(2/3)x=1/2
(2/3)x=1/2-3/4=2/4-3/4=-1/4
x=(-1/4):2/3=-3/8

(5/6)a=(2/3)a+2
(5/6)a-(2/3)a=2
(5/6)a-(4/6)a=2
(1/6)a=2
a=2:(1/6)=12
