Question

x+21=2x-13 find the value of x​

Answer 1

Answer:

Step-by-step explanation:

Simplifying

21 + -2x = 13

Solving

21 + -2x = 13

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-21' to each side of the equation.

21 + -21 + -2x = 13 + -21

Combine like terms: 21 + -21 = 0

0 + -2x = 13 + -21

-2x = 13 + -21

Combine like terms: 13 + -21 = -8

-2x = -8

Divide each side by '-2'.

x = 4

Simplifying

x = 4

Answer 2

Answer:

x+21=2x-13

= x-2x = -13-21

= -x = - 34

= x= 34

THE RIGHT ANSWER IS 34.
