2p+6a=$14
3p+9a=$21
3p+9a=21
Subtract 9a
3p=21-9a
divide all by 3
p=7-3a
plug it into start equations
2p+6a=14
2(7-3a)+6a=14
14-6a....+6a=14
this zeroes out...
Answer:
f(x)-3x+5 and g(x)=4+5 is it true ?Step-by-step explanation:
6x+1 = 3(2x-4)
-4(x+3) = 4(x-1)
Ok so divide 39 by 4 which is 9.75 then mulitiply that by 3 to get your answer of $29.25
