3a + 27 = 01. First you subtract 27 from both sides to isolate 3a, the variable.3a = -272. Divide both sides by 3 to get a by itselfa = -9The final answer is a = -9
the answer is -3x = 0
If 5 x equals 9 plus 2x then x equals?
3x + 2 = 82
7(3y-2)-(-4y+9)
13a - 6 + a = 5a + 3 + 3a 13a + a - 5a - 3a = 3 + 6 6a = 9 6a/6 = 9/6 a = 3/2
11a-3a =8a so 8a+9=-7 8a = -16 a=-2
3a squared plus nine = 19a. 3a to the second power = 9a plus 9 = 19a.
Yes.
The given expression does not have rational factors, so the question cannot be abut factorising. Evaluating x2 - 14x + 9 depends on the value of x.
a = 9
4a+3-a =12 4a-a = 12-3 3a = 9 a = 3
(3 x 3) - 6 = 3 3a-6=3 3a=3+6 3a=9 a=9/3 a=3
Gathering like terms together, this can be rewritten: 9a = 180 Dividing both sides of the equation by 9: a = 20
5a+95 :D
9 - 3a = 8Add 3a to each side:9 = 8 + 3aSubtract 8 from each side:1 = 3aDivide each side by 3:1/3 = a
a2 - 6a + 9 = a2 - 3a - 3a + 9 = a(a - 3) - 3(a - 3) = (a - 3)*(a - 3) = (a - 3)2
