Question

solve the question
$2x - 3(4x + 1) = 7$
​

Answer 1

Answer:

2x-3(4x+1)=7

2x-12x-3=7

-10x=7+3

-10x=10

x=10/-10

x=-1

Answer 2

Answer:

$\Huge \boxed{X=-1}$

Step-by-step explanation:

To solve this problem, first you have to isolate it by the x from one side of the equation.

First, expand the form to use distributive property.

Distributive property=$\displaystyle a(b+c)=ab+ac$.

$\displaystyle -3(4x+1)=-12x-3$

$\displaystyle 2x-12x-3=7$

Next, add similar to elements from left to right.

$\displaystyle 2x-12x=-10x$

$\displaystyle -10x-3=7$

Then, add 3 from both sides.

$\displaystyle -10x-3+3=7+3$

Solve.

$\displaystyle 7+3=10$

$\displaystyle -10x=10$

Now, divide by -10 from both sides.

$\displaystyle \frac{-10x}{-10}=\frac{10}{-10}$

Solve.

$\displaystyle 10\div-10=\boxed{-1}$

$\bigstar\large\boxed{\textnormal{Therefore, the correct answer is \boxed{X=-1}}}}}}.\bigstar$
