isolate the variable
21.50t=495
divide both sides by 21.50
t=approx 23.02
63+18t=495
move 63 over by changing sign
18t=495-63
18t=432
divide both sides by 18
t=24
Answer: I am guessing that you needed each equation solved?
Step-by-step explanation:
t= 495/21.5
t=23.02
63+18t=495 (subtract 63 from both sides)
18t=432 (divide both side by 18)
