Question

x + 3 = 2x - 7 what is the solution ​

Answer 1

Answer:

The value of x is 10

Step-by-step explanation:

⇒x+3=2x−7

• Subtract 2x from both sides.

⇒x+3−2x=−7

• Combine x and −2x to get −x.

⇒−x+3=−7

• Subtract 3 from both sides.

⇒−x=−7−3

• Subtract 3 from −7 to get −10.

⇒−x=−10

• Multiply both sides by −1.

⇒x=10

Answer 2

Answer:

The value of the expression is $10.$

Step-by-step explanation:

In context to questions asked,

We have to determine the value of the expression,

Given that:-

$x + 3 = 2x - 7$

Now subtract both sides by $3$, we get  

=> $x + 3 -3= 2x - 7-3$

=> $x = 2x - 7-3$

Subtract the number,

=> $x = 2x - 10$

Subtract both sides by $2x$,

=> $x -2x= 2x - 10-2x$

=> $-x= -10$

Divide both sides by $-1$, we get

=> $x = 10$
