Question

Rezolvati: 5x - 4=2x + 8

Answer 1

5x-4=2x+8
5x-2x=8+4
3x=12
x=12:3
x=4

Answer 2

5x - 4 = 2x + 8 

5x - 2x = 8 + 4 

3x = 12 

3x/3 = 12/3 

x = 4 Simplifying 5x + -4 = 2x + 8
Reorder the terms: -4 + 5x = 2x + 8
Reorder the terms: -4 + 5x = 8 + 2x
Solving -4 + 5x = 8 + 2x
Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-2x' to each side of the equation. -4 + 5x + -2x = 8 + 2x + -2x Combine like terms: 5x + -2x = 3x -4 + 3x = 8 + 2x + -2x Combine like terms: 2x + -2x = 0 -4 + 3x = 8 + 0 -4 + 3x = 8 Add '4' to each side of the equation. -4 + 4 + 3x = 8 + 4 Combine like terms: -4 + 4 = 0 0 + 3x = 8 + 4 3x = 8 + 4 Combine like terms: 8 + 4 = 12 3x = 12 Divide each side by '3'. x = 4 Simplifying x = 4
