Answer 1

Respuesta:

x = 3

Explicación paso a paso:

2×+6+3x=21+4x-2x-6

5x + 6 =21+4x-2x-6

5x + 6 =21+2x-6

5x + 6 =2x + 15

5x - 2x = 15 - 6

3x = 9

x = 9/3

x = 3

comprobación

2×+6+3x=21+4x-2x-6

2 * 3 + 6 + 3 *3 = 21 + 4 * 3 - 2 * 3 - 6

6 + 6 + 9 = 21 + 12 - 6 - 6

6 + 6 + 9 = 21 + 12 - 6 - 6

12 + 9 = 33 - 6 - 6

21 = 33 - 12

21 = 21 ✅✅
