Question

Solve for x: -
25 – 3x = 4

Answer 1

25 - 3x =4

-3x = 4- 25

-3x = -21

3x = 21

x = 21/3

x =7

Answer 2

Answer:

x-7

Step-by-step explanation:

Simplifying

25 + -3x = 4

Solving

25 + -3x = 4

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 = 4 + -25

Combine like terms: 25 + -25 = 0

0 + -3x = 4 + -25

-3x = 4 + -25

Combine like terms: 4 + -25 = -21

-3x = -21

Divide each side by '-3'.

x = 7

Simplifying

x = 7
