+33616 Start by multiplying out the brackets on both sides of the equation:
0.3(6 + p) = 0.4(8 - p)
0.3*6 +0.3*p = 0.4*8 -0.4*p
1.8 + 0.3*p = 3.2 - 0.4*p
Add 0.4*p to both sides and subtract 1.8 from both sides
0.3*p + 0.4*p = 3.2 - 1.8
Collect similar terms
0.7*p = 1.4
Divide both sides by 0.7
p = 1.4/0.7
p = 2
