. What is the value of x in the solution to this system of equations?

y = 2x – 6

y = -4x + 6

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Me! i really need to get this right before 9. prove the divisibility of 7^6+7^5-7^4 by 11. use factoring so you get a number times 11. just tell me the number. i need this done asap

What is a correct first step in solving the inequality-4(3-5x)> -6x+9
