Answer:
To find the value for x you need to get x by itself
To do this we need to do the opposite of what it is showing
1.5 times x the opposite would be dividing
So we need to divide 1.5 from each side (what you do to one side you do to the other)
1.5x/1.5=x (x is now by itself)
3/1.5=2
x=2
Hope this helps ;)
