If 5 x equals 9 plus 2x then x equals?
x+2=9 x=9-2 x=7
What is x in 3x-9 EQUALS 27? X= 36 THIS IS THE WORK: 27 + 9= 36 36/3= 12 :)
-23
y = 3x + y => x = 0then y = x - 9 => y = 0 - 9 = -9.
9 x 20 = 180
x = 20
x = -9
This is not correct. If x=11, then 9+x=20. In order for 9+x=21 to be correct, x would have to be equal to 12.
Subtract 9 from each side. ( subtraction; both sides ) X + 9 = 20 X + 9 - 9 = 20 - 9 X = 11 -----------------check in original equation 11 + 9 = 20 20 = 20 checks
If x=9, x=9
20
6x-20 = 34 +20 +20 6x = 54 /6 /6 x = 9
One equation y equals 9 x equals 14 Don't forget to add it to 23.
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
