Question

Solve for x
3 (x – 4) = 12x

Answer 1

X =
`(-4)/(3)`

Explanation:

Step 1: Simplify both sides of the equation.

3(x−4)=12x

(3)(x)+(3)(−4)=12x(Distribute)

3x+−12=12x

3x−12=12x

Step 2: Subtract 12x from both sides.

3x−12−12x=12x−12x

−9x−12=0

Step 3: Add 12 to both sides.

−9x−12+12=0+12

−9x=12

Step 4: Divide both sides by -9

`(-9x)/(-9) =(12)/(9)`

X
`=(-4)/(3)`

Answer:

`=(-4)/(3)`
