450+added
S=450+70W would be the equation
then afet 19 weeks
W=19
S=450+70(19)
S=450+1330
S=1780
equation is
S=70W+450
after 19 weeks, has 1780

Step-by-step explanation:
You move the +4a to the left side of the equal sign and that becomes a negative
9a-2-4a=c
You move -2 to the right side of the equal sign and that becomes a positive
9a-4a=c+2
Combine like terms
5a=c+2
Divide by 5 from each side
a=(c+2)/5
