-5
it equals 300
x2-35x+300 = 0 (x-15)(x-20) = 0 x = 15 or x = 20
2x - 5 = 15 2x = 20 x = 10
X = 1
20
5x5=25. 5, 10, 15 , 20, 25.
13x + 15 = 11x - 5 2x = -20 x = -10
x = 15
x=6=x=5+x=13+x=20 x cannot = x+5. This question has no answer.
If the question is, What x 3 equals 15? Then 5 x 3 = 15 If the question is, What is 15 x 3? Then 15 x 3 = 45
-3x + 5 = 20 -3x = 15 x = -5
