What is the value of x? 6x−2(x 4)=12 x=?

Let's solve your equation step-by-step.6x−2x4=12x−2x4+6x=12x
Step 1: Subtract 12x from both sides.−2x4+6x−12x=12x−12x−2x4−6x=0
Step 2: Factor left side of equation.2x(−x3−3)=0
Step 3: Set factors equal to 0.2x=0 or −x3−3=0x=0 or x=−1.44225
x=0 or x=−1.44225 This is the answer if its exponent. The other might be:
Step 1: Simplify both sides of the equation.6x−2(4x)=12x
Simplify: (Show steps)−2x=12x
Step 2: Subtract 12x from both sides.−2x−12x=12x−12x−14x=0
Step 3: Divide both sides by -14.−14x−14=0−14x=0
You never specified what the (x4) part was so I gave both.
