2.6(5.5p-12.4)=127.92
Divide both sides by 2.6:
5.5p-12.4=49.2
Add 12.4 to both sides:
5.5p=61.6
Divide both sides by 5.5:
p=11.2

Distribute
2.6(5.5p – 12.4) = 127.92
14.3p - 32.24 = 127.92
Add 32.24 on both sides to cancel out - 32.24
14.3p = 160.16
Dived both sides by 14.3 to make p alone
p = 11.2
