Answer:
Simplifying
7x + -9y2 = 0
Solving
7x + -9y2 = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '9y2' to each side of the equation.
7x + -9y2 + 9y2 = 0 + 9y2
Combine like terms: -9y2 + 9y2 = 0
7x + 0 = 0 + 9y2
7x = 0 + 9y2
Remove the zero:
7x = 9y2
Divide each side by '7'.
x = 1.285714286y2
Simplifying
x = 1.285714286y2
Step-by-step explanation:
hope it helps you dear ❤️
