32% because the total students surveyed was 50 and 18 of them have a plan with texting so if you multiply that by 2 you’re left with 32%

I assume you mean:

(2x-10)/4=3x  multiply both sides by 4

2x-10=12x  subtract 12x from both sides

-10x-10=0  add 10 to both sides

-10x=10  divide both sides by -10

x=-1
