Question

For what value of x will the lines lan
(3x - 20
(2x + 10)​

Answer 1

Answer:

$\large\boxed{x=30}$

Step-by-step explanation:

To find the value of x, first you have to isolate x on one side of the equation.

Given:

(3x-20)=(2x+10)

First, expand and make sure to use distributive property.

$\large\boxed{\textnormal{Distributive property}}$

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

You can also remove parenthesis.

$\displaystyle (2x+10)=2x+10$

Solution:

3x-20=2x+10

Next, add 20 from both sides.

$\displaystyle 3x-20+20=2x+10+20$

Solve.

$\displaystyle 20+10=30$

$\displaystyle 3x=2x+30$

Then, subtract 2x from both sides.

$\displaystyle 3x-2x=2x+30-2x$

Solve.

$\large\boxed{x=30}$

x=30, which is our answer.

Answer 2

$\red {\huge {\underline{ \frak{Your \: answEr : }}}}$

➟ (3x - 20) = (2x + 10)

➟ 3x - 2x = 10 + 20

➟ x = 30
