It is not possible to answer the question as the value of a is not known, if the value of a was known, for example 2, you could answer as 6a would be 2x6 which is 12 plus 4 giving a total of 16
until the value of a is known the most correct solution, including the brackets, would be (6a+4)
-4 + 10 + 6a - 2a + 3 9 + 4a
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
6a + 2
9a = 6a + 4 subtracting 6a from each side, 3a = 4 dividing each side by 3, a = 4/3
=6a
It is 6a + 4
4y - 4 + 3s + 7 - 6a - 4 = 0 4y + 3s + 7 - 6a - 4 = 4 4y + 3s - 6a - 4 = 4 -7 4y + 3s -6a = 4 - 7 + 4 4y + 3s - 6a = -3 + 4 4y + 3s - 6a = 1 y + 3s - 6a = 1/4 y = -3s + 6a + 1/4 3s = -y + 6a + 1/4 s = -1/3y + 6a + 1/4 -6a = -1/3y + a + 1/4 -a = -1/3y x 1/6 + a + 1/4 x 1/6 a = 1/18y - 1 - 1/24 a = 1/18y - 25/24
34
a+6a+a=8a
6a plus 18b = 24
6a
6a + 8 = 2(3a + 4)
