Answer 1

D

Explanation:

Given

11x = 11 - 55xz²

Collect the terms in x together by adding 55xz² to both sides

11x + 55xz² = 11 ← factor out x on the left side

x(11 + 55z²) == 11 ← divide both sides by 11 + 55z²

x =
`(11)/(11+55z^2)` ← factor out 11 on the denominator

x =
`(11)/(11(1+5z^2))` ← cancel 11 on numerator/denominator

x =
`(1)/(1+5z^2)` → D
