Solve for x in the equation: 2x-7=14

x=10.5

Step-by-step explanation:

To solve for x, we want to use our properties to isolate x.

2x-7=14           [add both sides by 7]

2x=21              [divide both sides by 2]

x=10.5

Now, we know that x=10.5.

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
