Answer:
x=7
Step-by-step explanation:
3x + 2(4 + 6x)= 113
you multiply 2 to 4 that gives you 8 and 2 to 6 that gives you 12x because the 6 has x on it
so it will be 3x + 8 + 12x= 113 then you add 3x to 12x
then you would have 15x+8=113 then subtract 8 to 113 then divide that number to 15 and you get x=7
