Question

a) 6+2× = 15-×
b) 3×-15 = -6×+12​

Answer 1

Respuesta:

a) X = 3

b) X = 3

Explicación paso a paso:

a) 6+2× = 15-×

2x+x = 15-6

3x = 9

x = 9/3

x = 3

Comprobación

6+2× = 15-×

6+2(3) = 15-(3)

6+6 = 12

12 = 12

b) 3×-15 = -6×+12

3x+6x = 12+15

9x = 27

x = 27/9

x = 3

Comprobación

3×-15 = -6×+12

3(3)-15 = -6(3)+12

9-15 = -18+12

-6 = -6
