x=1
x^2 +9 =x^2 -9 9=-9 No solution
The value of x that satisfies -9 multiplied by x equals 1 is x = -1/9.
x + 5 - 2x = 9 -x = 4 x = -4
5. Just do 9 minus 4. 5 plus 4 equals 9
x=1
X= 2!
Well if 3x+9=5 x=? Well you minus 9 from the side and then do 5-9 and that equals -4. Then you have to do -4 divided by 3. Which equals -1 so I believe x will equal -1.
x^2 +9 =x^2 -9 9=-9 No solution
The value of x that satisfies -9 multiplied by x equals 1 is x = -1/9.
x + 5 - 2x = 9 -x = 4 x = -4
5. Just do 9 minus 4. 5 plus 4 equals 9
x= -11
x = √(2-x) x2 = 2-x x2 + x = 2 x2 + x - 2 = 0 (x+2)(x-1) = 0 x = 1 or -2
5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
It is a quadratic equation and its solutions are: x = -3/2 and x = 3
x * x - 9 = 0 PEMDAS = Multiplication first. What multiplied it self equals nine? 3. So x = 3
