Switch it to make p7 7p = p7
7p
5p + 15p + 7p = 27p 5p - 15p + 7p = -3p 5p x 15p + 7p = 75p2 + 7p 5p/15p + 7p = 7p + 1/3
7p-10p = -3
7p-2p equals = 5
3p +12= 7p 7p-3p=12 12?3=4 p=4
2p+7p = 9p simplified
6nx + 7p - 14p + 2nx + 6x = 8nx - 7p + 6x
8p+5 = 11+7p= 8p-7p = 11-5p = 6
To solve this group together the like terms. 7p + -p = 6p Then the answer is 6p -9.
4p + 9 + (-7p) + 2 = 4p - 7p + 9 + 2 = -3p + 11
7 50p / 7p pencil = 7.14 pencils. But obviously, you can't buy 0.14 of a pencil so the answer is 7, and you'd have 1p left over.
