Answer:
x = ±2
Step-by-step explanation:
9x^2-36=0
Using the square root property
9x^2 = 36
Divide each side by 9
x^2 = 4
Take the square root of each side
sqrt(x^2) = sqrt(4)
x = ±2
2 dimes = $0.20
2 dollars = $2.00
20 cents = 10% of 2 dollars
Using the elimination method, the value of x in the system of equations is calculated as: 8.
<h3>How to Solve a System of Equations by Elimination?</h3>
To solve a system of equations given using the elimination method, do the following:
Multiply 2x - 5y = 1 by 2 and multiply -3x + 2y = -18 by 5 to get the following:
4x - 10y = 2 --> eqn. 1
-15x + 10y = -90 --> eqn. 2
Add
-11x = -88
Divide both sides by -11
x = 8
