Question

resolver
a) 15/2 + 3x =2x + 3/2
b) 3x/2 - 1/2 = x/4 + 8/5 + x/2

Answer 1

15/2+(3x)=(2x)+3/2
15/2+(3x-2x)=3/2
15/2+(x)=3/2
x=3/2-15/2
x=-12/2


(3x/2=6x/4) y tambien (x/2=2x/4)

(3x/2)-1/2=(x/4)+8/5+(x/2)
(3x/2)-(1/2)=(x/4)+(2x/4)+8/5
(3x/2)-1/2=(3x/4)+8/5
(6x/4)-(3x/4)=8/5+1/2
(3x/4)=(21/10)
x=(21x4)/(3x10)
x=84/30
x=14/5
