X = the brother
c = carly
c = 3x
c + x < = 24
now we sub
3x + x < = 24
4x < = 24
x < = 24/4
x < = 6 ...oldest age the brother can be is 6

5y+2x=10y=−25x+2246810−2−4−6−8−10246810−2−4−6−8−10Let's solve for x.5y+2x=10Step 1: Add -5y to both sides.2x+5y+−5y=10+−5y2x=−5y+10Step 2: Divide both sides by 2.2x2=−5y+102x=−52y+5Answer:x=−52y+5
You have to fill in 3 for x so it woul look like 3x3-3 and that would be 6.
