2​

Answer 1

Answer:

Simplifying

25 + 3x = 13

Solving

25 + 3x = 13

Solving for variable 'x'.

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

Add '-25' to each side of the equation.

25 + -25 + 3x = 13 + -25

Combine like terms: 25 + -25 = 0

0 + 3x = 13 + -25

3x = 13 + -25

Combine like terms: 13 + -25 = -12

3x = -12

Divide each side by '3'.

x = -4

Simplifying

x = -4

Answer 2

Step-by-step explanation:

25 - 3x = 13

- 3x = 13 - 25

- 3x = - 12

3x = 12

x = 12/3

x = 4.
