Answer:
x = 7/3
Step-by-step explanation:
<u>Given equation:</u>
To determine the value of "x", we need to isolate the x-variable and it's coefficient on one side of the equation. This can be done by subtracting 49 to both sides of the equation.
- ⇒ –9x² + 49 - 49 = 0 - 49
- ⇒ –9x² = -49
We can see that the negative sign in on both sides of the equation. Remove it by dividing -1 to both sides of the equation.
- ⇒ –9x² = -49
- ⇒ -9x²/-1 = -49/-1
- ⇒ 9x² = 49
Clearly, we can see that 9x² and 49 are perfect squares. Therefore,
Take square root both sides of the equation:
To determine the value of "x", we need to isolate it "completely". This can be done by dividing 3 to both sides of the equation
Therefore, the value of "x" must be 7/3.
