solve using the multiplication principle.
1/2x=3/4

the way you typed it...
multiply each side by 2
(2)(1/2)x = 2(3/4)
x = 3/2 
can you check if i have this one right 0.6x+2=1.4x1
my answer is ¡Ý 3.75 im i correct 
"can you check if i have this one right 0.6x+2=1.4x1
my answer is ≥ 3.75 im i correct"
You have correctly solved the equation to get x=3/0.8 = 3.75.
However your statement of x≥3.75 would be incorrect since the question given is an equation, and not an inequality.
