The equation (5a = n) expresses a relationship between the variables (a) and (n), indicating that (n) is equal to five times the value of (a). To solve for (a), you can rearrange the equation to (a = \frac{n}{5}). This means that if you know the value of (n), you can find (a) by dividing (n) by 5.
If: -5a = 300 Then: a = -60
(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)
2a+5a+9a = 16a
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
A= 2
If: -5a = 300 Then: a = -60
(5a).7 = -23 7(5a) = -23 35a = -23 a = -23/35 a= -0.657 (3 d.p.)
Answer to: 5a + 1 = a - 3a = -1
Divide 5a and 180 by 5. a = 36
5a = -5a + 5Add 5a to each side:10a = 5Divide each side by 10:a = 5/10 = 1/2
2a+5a+9a = 16a
If: 5a-1+a = 11 Then: a = 2
The statement is false. 5a +6 = 5a + 30 Subtract 5a from both sides: 6 = 30 and that is plain and simple rubbish!
a + 3a + 5a = 180 9a =180 a = 20
7a + 4 = 5a + 7 7a = 5a + 3 2a = 3 a = 3/2
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6
A= 2
