Question

solve for x. 3(x- 4)=15x​

Answer 1

Answer:

x=-1

Step-by-step explanation:

3(x−4)=15x

Use the distributive property to multiply 3 by x−4.

3x−12=15x

Subtract 15x from both sides.

3x−12−15x=0

Combine 3x and −15x to get −12x.

−12x−12=0

Add 12 to both sides. Anything plus zero gives itself.

−12x=12

Divide both sides by −12.

x=  

−12

12

​  

 

Divide 12 by −12 to get −1.

x=−1

Answer 2

Answer:

$3(x- 4)=15x$

$3x-12=15x$

$3x-12+12=15x+12$

$3x=15x+12$

$3x-15x=15x+12-15x$

$-12x=12$

$\frac{-12x}{-12}=\frac{12}{-12}$

$x=-1$
