He currently does 8, and is increasing by 2, so our equation will be

2x+8=30

Subtract the 8 over

2x=22

Divide by 2 on both sides

X=11

It will take 11 days

Answer:

x= 2

So therefore we first work out it takes 12 days so we cna condense this to 6x and make the equation -4x+6x = 12 to find how many press ups he used to do.

To find day increase = (x+5x) = 6x = 12

Or to find amount of press ups per day = 3x x 5x =30
