X + 13 = 25
Explain what is happening to the variable

x=12

x is being isolated

Step-by-step explanation:

I'm assuming you mean to solve for x? if so

you have to first isolate x

x+13=25 subtract 13 from both sides

-13 -13

x= 12 there's ur answer

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
