8x+6(x-1)=3(4x+1)

Question

math equations the answer

Answer 1

8x + 6(x-1) = 3(4x+1);

8x + 6x - 6 = 12x + 3;

14x - 6 = 12x + 3;

2x - 6 = 3;

2x = 9;

x = 9/2 = 4.5

Answer 2

Use the distributive property first to expand the equation.  8x+6(x-1)=3(4x+1)     8x+6x-6=12x+3

Next use the inverse property of addition to put the variables on the left side and the constants on the right.        8x+6x-6= 12x+3      8x+6x-6[+6] [-12x]=12x[-12x] +3 [+6]     8x+6x-12x=3+6

Add the variables and constants.  8x+6x-12x=3+6    2x=9

Isolate the variable by dividing the 2.    2x=9     x=9/2  or  x=4.5

Answer 3

8x + 6(x-1) = 3(4x + 1)

First, expand the formulas, then solve for x:

8x + 6x - 6 = 12x + 3

8x + 6x - 12x -6 + 6 = 12x - 12x + 3 + 6

2x = 9

x = 9/2 = 4.5
