Answer:
Step-by-step explanation:
1. x/64 = 36/x
x^2 = 2304
x=48
2. 9/x = x/25
x^2 = 225
x=15
3. x/16 = 9/x
x^2 = 144
x=12
4. 45/x = x/81
x^2 = 3645
x=27
First we distribute 3 into 2x and -4.
3 x 2x = 6x
3 x -4 = -12
That will make the left side of the equation:
6x - 12 = 5x + 2
Now we subtract 5x on both sides of the equation.
x - 12 = 2
Finally we add 12 on both sides of the equation.
x = 14 is the answer
