11a-3a =8a so 8a+9=-7 8a = -16 a=-2
a=5: c=4
8a/-9=12 8a=12x-9 8a=-108 a=-108/8 a=-13.5 Hence the required answer is -13.5
1+9+25=35 not 41, this is a false statement
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
2a + 21 = 8a - 9Add 9 to each side:2a + 30 = 8aSubtract 2a from each side:30 = 6aDivide each side by 6:5 = a
The answer is 41.
2x2x8 plus 9 is 41.
7/20 + 3/9 = 41/60
9 plus 87 equals 96.
12 plus 9 equals 21.
it could be anything. What is a? if it is 3 then you do 4x3=12+3x3=9+3=24 * * * * * It is 8a.
