If a + b = 6, what is the value of 3a + 3b?
Whichever of them, if any, equals 9.
2.5 plus 6 plus 3 equals 2.5 plus 6 plus 3
The value of x is 4/3
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
If a + b = 6, what is the value of 3a + 3b?
Whichever of them, if any, equals 9.
No! It equals 15, but 9-6=3.
2.5 plus 6 plus 3 equals 2.5 plus 6 plus 3
That depends entirely on what the value of z is.
The value of x is 4/3
No.
If 3x + 3 = 2x + 6 then 3x - 2x = 6 - 3 x = 3
3 is the true!
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
2/3 plus 4/6 equals 1 1/3. 2/3 has the same value as 4/6 so in effect you are adding 4/6 and 4/6 together, which equals 8/6 or 1 1/3.
2x + 3 = 6 2x = 3 x = 3/2 = 1.5
