Question

ayudenme porfavor :(​

Answer 1

Respuesta:

a = 12x + 8

b = 6x + 12

c = 16a

d =  7x + 8

a + b = 18x +

b + d = 13x + 20

no estoy segura si así sea :(

Explicación paso a paso:

a. 3x + 2 × 4 = 12x + 8

b. (x + 5 · 2) + (2x + 1 · 2) = (2x + 10) + (4x + 2) = 6x +12

c. (4a · 2) + 3a + (2a · 2) + a = 8a + 3a + 4a+ a = 16a

d. (3x + 2) + (2x + 1) + (x+ 3) + (x+2) = 7x + 8

a + b = (12x+8) + (6x+12) = 18x + 20

b + d = (6x+12) + (7x+8) = 13x + 20
