Answer:
2c <u><</u> 19
Step-by-step explanation:
Its not giving you an exact value of what c is so when you see "at most 19" you would use less than or equal to sign ( <u><</u> <u>)</u> but if instead said it "at least 19" you would use a greater than or equal to sign ( <u>></u> <u>)</u>.

2x+2=?x+13
Let x=2
2x+2=2x+13
Subtract 2x from each side
2 =13
This is never true so there is no solution
