Can someone tell me the answer and explanation plz I’ll give brainlist and points

 X = 60

Step-by-step explanation:

60+220=280

x = 60

Step-by-step explanation:

So, in order to isolate the x variable, get rid of the number on the same side of it, which is 220. Bring 220 over to the otherside of the equation and switch the sign. Since the 280 is already there, you subtract 280 from 220 to get 60.

x = 280-220

x = 60

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
