Respuesta:
3(x + 2) = 21
3x + 6 = 21
3x = 21 - 6
3x = 15
x = 5
2(b - 5) = b - 7
2b - 10 = b - 7
2b - b = -7 + 10
b = 3
x + 4 = 2(2 + x) - 5
x + 4 = 4 + 2x - 5
x + 4 = 2x - 1
4 + 1 = 2x - x
5 = x
x + (x + 2) + (x + 4) = 12
x + x + 2 + x + 4 = 12
3x + 6 = 12
3x = 6
x = 2
4(a + 5) - 4 = 2(4 - a) + 6
4a + 20 - 4 = 8 - 2a + 6
4a + 16 = 14 - 2a
4a + 2a = 14 - 16
6a = -2
a = -1/3
6(x + 2) = 15x + 9
6x + 12 = 15x + 9
12 - 9 = 15x - 6x
3 = 9x
1/3 = x
2(y + 3) + 4y = 4(y - 3) + 17
2y + 6 + 4y = 4y - 12 + 17
6y + 6 = 4y + 5
6y - 4y = 5 - 6
2y = -1
y = -1/2
3(x + 6) - x + 4 = 3(2x + 10) + 8
3x + 18 - x + 4 = 6x + 30 + 8
2x + 22 = 6x + 38
22 - 38 = 6x - 2x
-16 = 4x
-4 = x
5(x + 1) = 2x + 2
5x + 5 = 2x + 2
5x - 2x = 2 - 5
3x = -3
x = -1
2(m + 2) = m + 1
2m + 4 = m + 1
2m - m = 1 - 4
m = -3
