x=9
Step-by-step explanation:
when subtracting 7x by 4x one gets the answer of 3x because the coefficients are the same (7x-4x=3x) Then you have to set your answer of 3x to 27 (3x=27)
Being you are trying to get x by itself you divide three from the whole statement, so (3x/3=27/3) the answer would then be 9 because 27 divided by 3 is 9
