9p+1 = 1p+3 Take away 1p from each side: 8p+1=3 Take away 1 from each side: 8p = 2 Divide both sides by 8: p = 2/8 = 1/4

2p - 16 = 37 + 9p(1) you need to gather like terms on each side, the variable & numbers. add 16 to both sides.2p - 16 + 16 = 37 + 9p + 162p = 53 + 9p(2) now subtract 9p from both sides to get:2p - 9p = 53+9p - 9p-7p = 53(3) now divide each side by -7-7p/-7 = 53/-7p = -53/7
126 + 1 + 290 = 417
If you mean 3 pence, there are two ways, 3 x 1p coins or 1 x 1p plus 1 x 2p coin.
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
Let S = Pair of Scissors J = Jar of Paste and P = Pencils Then 1S + 2J = 8P 1J = 1S + 1P From the second equation, 1S = 1J - 1P Substitute this value in the first equation: 1J - 1P + 2J = 8P so that 3J - 1P = 8P or 3J = 9P J = 3P Three pencils will balance 1 jar.
