12 (6x + 4) + 5x -8
First you’d need to distribute the 12 in order to begin combining like terms.
72x + 48 +5x -8
Circle which have an exponent which would be 72x and +5x which would be 77x
Box the numbers without exponents and combine those 48 -8 which equals 40
77x + 40
There is no number that these two share so there is no way for them to be simplified so your answer is just 77x + 40.
