a + 6a - 9 = 30
7a - 9 = 30
7a = 30 + 9
7a = 39
a = 39/7
a = 5.571 (to 3 decimal places only).

Calcuate the quantity of x and it's maximum error if x equals 6a plus 4b where a equals 40 tolerance is plus or minus 2 and b equals 20 plus or minus 2?
320 tolerance +/- 20 ? Did I get it right?
If 26 equals 30 minus 6a what does a equal?
26 = 30 - 6a Taking 30 off each side gives, 26 - 30 = -4 = -6a Dividing each side by -6 gives, -4 / -6 = a, thus a = 2/3 or 0.667
-6a plus 8 equals 2?
-6a + 8 = 2 -6a = -6 a = 1
3(6a plus 5) plus 30?
3(6a + 5) + 30 18a + 15 + 30 18a + 45
What is the answer to 6a plus 2 equals 2a plus 10?
A=2

What is 3a plus 5b minus 6a minus 9b?
3a + 5b - 6a - 9b = -3a - 4b
-6a plus 8 equals 2?
-6a + 8 = 2 -6a = -6 a = 1
Factor 6a-8ab plus 2a?
6a to the second power minus 8ab + 2a
5a plus 5 equals 6a-7 equals?
5a+5=6a-7
What is 30 equals 6a?
A=5How to do it:30=6aa=6/6 (Do on both sides) 30/6a=(6/6 cancels out) 30/6a=5
3(6a plus 5) plus 30?
3(6a + 5) + 30 18a + 15 + 30 18a + 45
Factorise 6a-12b plus 30?
6a -12b + 30 = 6 (a - 2b + 5)
What is the answer to 6a plus 2 equals 2a plus 10?
A=2
