Multiply everything by 4 because it's the lcm

X+3+2x=6

X+2x=6-3

3x= 3

Divide both side by 3

X= 1

(X + 3)/4 + X/2 = 3/2

Solution

The LCM is 4

Multiply through using the LCM

4( X + 3)/4 + 4(X /2) = 4(3/2)

X + 3 + 2X = 2x3

X +3 + 2X = 6

3X +3 = 6

3x = 6 -3

3x = 3

X = 1

Therefore X is 1
