Answer:
w = 42
Step-by-step explanation:
-w/6 + 9 = 2
subtract 9 from both sides
-w/6 + 9 - 9 = 2 - 9
-w/6 = 2 - 9
-w/6 = -7
multiply both sides by -6
-w/6 * -6 = -7 * -6
w = -7 * -6
w = 42
The resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions
<h3>Quadratic equations</h3>
Quadratic equations are equations that has a leading degree of 2. Given the following system of equations
y=2x
y=x^2+2
Equate to have:
2x = x^2+ 2
Equate to zero
x^2 - 2x +2 = 0
Since the resulting equation has a leading degree of 2, hence the system of equation will have 2 solutions
