Question

3p-4=8and 2p=4 is it equivalent

Answer 1

3p-4=8
3p=12
p=4

2p=4
p=2

So no, they are not equivalent.

Hope this helps :)

Answer 2

3p-4=8
+4 on both sides to get
3p=12
divide each side by 3 to get p=4

2p=4
divide off 2 on both sides to get
p=2

Is 2=4? If it is then it is equivelent, if it isnt then theyre not.
