Hi Sam;
4(3x+4)2(3x7)
Your first priority is to distribute....
Let's begin with the first parenthetical equation...
4(3x+4)
12x+16
Second parenthetical equation...
2(3x7)
Note the fact that the subtraction sign is also a negative sign for the 2...
6x+14
Note the fact that 7, when multiplied by 2, becomes POSITIVE 14...
12x+166x+14
Let's combine like terms...
12x6x=6x and 16+14=30
6x+30
