Correct option is D
Given:
2(3x² − 6) − 3(2x² + 8x − 5) = 14
Solution:
2(3x² − 6) − 3(2x² + 8x − 5) = 14
(6x² − 12) − (6x² + 24x − 15) = 14
6x² − 12 − 6x² - 24x + 15 = 14
-24x + 3 = 14
-24x = 11
x =
Find the value of x satisfying: 2(3x² − 6) − 3(2x² + 8x − 5) = 14
Given:
2(3x² − 6) − 3(2x² + 8x − 5) = 14
Solution:
2(3x² − 6) − 3(2x² + 8x − 5) = 14
(6x² − 12) − (6x² + 24x − 15) = 14
6x² − 12 − 6x² - 24x + 15 = 14
-24x + 3 = 14
-24x = 11
x =
