Step-by-step explanation:
2hr=$12
1hr=12/2= $6/hr
$36=1hr/$6= 6hr for $36
If he worked 3hr he would get (6*3)= $18
If he worked 4 hours he would get (6*4)= $24
I hope this answers your question
5x + 2 must be equal to 17. Subtract to from both sides, then divide both sides by 5 and x = 3. 3y - 6 must equal 21. Add 6 to both sides, then divide both sides by 3, and y = 9.
