10p - 15 = 50
10p = 65
p = 65 / 10
p = 13 / 2
p = 6 ½

5(2p - 3) = 50
distributive property, so multiply 5 by 2p and -3
10p - 15 = 50
Add 15 to both sides of the equation
10p = 65
Divide by 10 on each side
p = 6.5

6.5
distribute 5(2p-3) or 10p-15= 50
then bring -15 to the other Side of the equal sign by adding
15+50= 65. then to get P alone divide 10 into 65.
and you get 6.5
(if you do a check it works out!)
: )
good luck

5(2p-3)
=10p-15 (by multiplying the equation)
but 5(2p-3)=50
therefore 10p-15=50 (since 5(2p-3)=10p-15)
10p=50+15
10p=65
p=65/10
p=6.5

5(2p-3)=50
10p-15=50
10p=50+15
10p=65
p=65/10
p=13/2 or6.5

10p - 15 = 50
10p = 50 + 15
therefore
p = (50 +15)/10
Sorry i couldnt be bothered working out the answer.. jus 2 lazy.
