2X+5=47 here are the rules to solving
Rule 1: look at the question
Rule 2: how many terms [in this case it is three]
Rule 3:Do the opposite operation of the number by 2X [the term you are solving for]. transfer the number to over the = sign
Rule 4: After the opposite operation divide the answer you got using the opposite operation with the variable you are solving for. so it is like this: 2X+5=47
opposite operation: 2x=47-5
2X=42
in order to let the x by itself divide the number by it
so 42 divided by 2 is 21.
