Question

resolver: 3x - 2 = 4x - 7 6x - 3 = 2x + 1 12x - 5 = 7

Answer 1

Respuesta:

1) X = 5

2) X = 1

3) X = 3/2

Explicación paso a paso:

1) 3X-2=4X-7

3X-4X = -7+2

-X = -5

X = 5

2) 6X-3 = 2X+1

6X-2X = 1+3

4X = 4

X = 4/4

X = 1

3) 12X - 5 = 13

12X = 13+5

12X = 18

X = 18/12

X = 3/2
