x=3 becaus: 6x=x+15 5x=15 (-x) x=3 (divided by 5)
If: x/3 + 10 = 15 Then: x = 15
-9
x=4
It is: x = 1.2
x=(-3)
x = 3
x2 + 2x - 15 = (x - 3)(x + 5)
x=4/3
x over 4= 2x+3 over 15
12 (x is -3)
The problem can be written as:46-3+7x-15 = 4243+7x-15=427x + (43-15) = 427x + 28 = 427x = 42 - 287x = 14x = 14/7 = 2
