10p+5= (18p - 6) / 2
Multiply both sides by 2 then
2(10p+5) = 10p -6
20p + 10 = 10p -6
Subtract 10p to both sides
20p +10 – 10p = 10p – 6 -10p
Simplify
10p +10 = -6
Subtract 10 to both sides
10p +10 – 10 = -6 -10
Simplify
10p = -16
Divide both sides by 10
10p/10 = -16/10
Simplify
P= - 16/10
P = -8/5
P = -1 3/5
