Question

Solve N=2rt^2-7rx for x​

Answer 1

N - 2 r t²

x = - ------------

7x

Explanation:

N = 2 r t² - 7 r x

solve for x

N = 2 r t² - 7 r x

N + (-2 r t²) = (2 r t² - 7 r x) + (-2 r t²)

N - 2 r t² = 2 r t² - 7 r x - 2 r t²

N - 2 r t² - 2 r t² + 2 r t² = - 7 r x

N - 2 r t² = 7 r x

therefore,

N - 2 r t²

x = - ------------

7x
