Question

10X – 4X + 4 = 10 + 4 - 8 + 4X
b.- 9X + 3X – 1 + 3 +3 = 6X + 5X+9

Answer 1

Explicación paso a paso:

10x - 4x + 4 = + 4 - 8 + 4x

6 + 4 = 10 + 4 - 8 + 4

6 + 4 = 6 + 4

6 + 4 - 4 = 4 + 6 - 4

6x = 4x + 2

6 - 4 = 4 + 2 - 4

2x = 2

2x/2 = 2/2

x = 1

9x + 3x - 1 + 3 + 3 = 6x + 5x + 9

9x + 3x + 5 = 6x + 5x + 9

12x + 5 = 6x + 5x + 9

12x + 5 = 11x + 9

12 + 5 - 5 = 11 + 9 - 5

12x = 11x + 4

12 - 11 = 11 + 4 - 11

x = 4
