Respuestas a la pregunta
b) 3.(x+2) = 15
3x+3.2 = 15
3x+6 = 15
3x = 15-6
x = 9:3
x = 3
c) 4.(x+5) = 28
4x+4.5= 28
4x+20 = 28
4x = 28-20
x = 8:4
x = 2
d) 5.(x+3) = 35
5x+5.3 = 35
5x+15 = 35
5x = 35-15
5x = 20
x = 20:5
x = 4
b) 3 (x + 2)= 15
3x + 6 = 15
3x = 15 - 6
x = 9/3
x = 3
c) 4 (x + 5)= 28
4x + 20 = 28
4x = 28 - 20
x = 8/4
x = 2
d) 5 (x + 3)= 35
5x + 15 = 35
5x = 35 - 15
x = 20/5
x = 4
e) 6 (x + 1)= 36
6x + 6 = 36
6x = 36 - 6
x = 30/6
x = 5
f) 7 (x + 6)= 49
7x + 42 = 49
7x = 49 - 42
x = 7/7
x = 1
