His mistake is that he didn't need to remove one even number on the spinner, so we just need to take 2/5×1/5=2/25.
|2x-3|=2x-3 ;x≥ 3/2
|2x-3|=-2x+3;x≤3/2
Answer:
x=13
Step-by-step explanation:
you have to isolate the variable
3(x-4)=x+14
distribute
3x-12=x+14
subtract 14 from each side
3x-26=x
subtract 3x from each side
-26=-2x
divide each side by -2
13=x
flip sides
x=13
