Question

-2.5=P+7.1. Find Pcan you explain me

Answer 1

-2.5=P+7.1

We want to isolate P.

Hence, we must move 7.1 to the left hand side, this can be given by

$-2.5-7.1=P$

that is, since 7.1 is adding to P on the right hand side, when you move it to the left hand side

7.1 must substract -2.5.

Finally, since

$-2.5-7.1=-9.6$

we have that

$P=-9.6$
