4(3x+4)-2(3x-7)

step 1: Multiply to get 12x + 16 - 6x + 14

step 2: Combine like terms

12x - 6x = 6x 16 + 14 = 30

step 3: The result is: 6x = 30

step 4: Divide each side by 6 to get "x" by itself

6x/6 = 30/6

x = 5

Hi Sam;

4(3x+4)-2(3x-7)

Your first priority is to distribute....

Let's begin with the first parenthetical equation...

4(3x+4)

12x+16

Second parenthetical equation...

-2(3x-7)

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+16-6x+14

Let's combine like terms...

12x-6x=6x and 16+14=30

6x+30
