The coefficient would be 2
Simplify the left hand side by multiplying the terms in the parenthesis by 3/4, i.e. divide them by 4 and multiply them by 3:

Subtract 6x from both sides:

Subtract 2 to both sides:

You will divide the 12 by 28: 12/28 and that equals 3/7
1.)11x^2-3x
2.)8x+1-x^2
3.)-x^2-x+8
4.)-2y+10-x^2
