Step-by-step explanation:
p=(5/8)q
(p+4)=2/3(q+4)
Distribute
p+4=2/3(q)+2/3(4)
Do math
p+4=2/3(q)+8/3
Substitute (5/8)q for p
(5/8)q+4=2/3(q)+8/3
Subtract 5/8(q) from both sides, subtract 8/3 from both sides
4–8/3=2/3(q)-5/8(q)
Find LCDs of fractions
12/3–8/3=16/24q-15/24q
Combine like terms
4/3=1/24(q)
Multiply both sides by 24
96/3=q
Reduce fraction
q=32
Substitute 32 for q
p=5/8(32)
Do math
p=20
