Answer:
i dont know
Step-by-step explanation:
-7x + 2x (add common factors)
-5x+6+21 (what happen to one side happens to the others
-5x=21 (divide by five)
x= -3
1 solution. it can't be 2, and if you solve it, there is a solution, x stays in the equation, so there's 1 solution

Answer:
x= 37/36
Step-by-step explanation:
−12(3x−4)=11
Step 1: Simplify both sides of the equation.
−12(3x−4)=11
(−12)(3x)+(−12)(−4)=11(Distribute)
−36x+48=11
Step 2: Subtract 48 from both sides.
−36x+48−48=11−48
−36x=−37
Step 3: Divide both sides by -36.
−36x
−36
=
−37
−36
x=
