Answer:
p=1
Step-by-step explanation:
2/5 + p = 4/5 + 3/5p
Multiply each side by 5 to clear the fractions
5(2/5 + p) = 5(4/5 + 3/5p)
2 +5p = 4 + 3p
Subtract 3p from each side
2+5p-3p = 4+3p-3p
2+2p = 4
Subtract 2 from each side
2+2p -2 = 4-2
2p =2
Divide by 2
2p/2 = 2/2
p=1
Nine less than a number
is
n - 9
Answer:
w=9x+4
Step-by-step explanation:
2(3x-3+w)=12x+2
6x-6+2w=12x+2
subtract 6x for both sides
-6+2w=18x+2
add 6 for both sides
2w=18x+8
Divide by 2 to find w
w=9x+4
